Chadwick A. "Chad" Trujillo (born November 22, 1973) is an American astronomer and the co-discoverer of the dwarf planetEris.
Trujillo works with computer software and has examined the orbits of the numerous trans-Neptunian objects (TNOs), which is the outer area of the solar system that he specialized in. In late August 2005, it was announced that Trujillo, along with Michael E. Brown and David L. Rabinowitz, had discovered Eris. As a result of the discovery of the satellite Dysnomia, Eris was the first TNO known to be more massive than Pluto.
Chad (i/tʃæd/; Arabic:تشادTshād; French:Tchad), officially the Republic of Chad (Arabic:جمهورية تشادJumhūrīyat Tshād; French:République du Tchad), is a landlocked country in Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon and Nigeria to the southwest and Niger to the west. It is the fifth largest country in Africa in terms of area.
Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the largest wetland in Chad and the second-largest in Africa. N'Djamena, the capital, is the largest city. Chad is home to over 200 different ethnic and linguistic groups. Arabic and French are the official languages. Islam and Christianity are the most widely practiced religions.
Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbers. By the end of the 1st millennium BC, a series of states and empires rose and fell in Chad's Sahelian strip, each focused on controlling the trans-Saharan trade routes that passed through the region. France conquered the territory by 1920 and incorporated it as part of French Equatorial Africa. In 1960, Chad obtained independence under the leadership of François Tombalbaye. Resentment towards his policies in the Muslim north culminated in the eruption of a long-lasting civil war in 1965. In 1979, the rebels conquered the capital and put an end to the south's hegemony. However, the rebel commanders fought amongst themselves until Hissène Habré defeated his rivals. He was overthrown in 1990 by his general Idriss Déby. Since 2003, the Darfur crisis in Sudan has spilt over the border and destabilised the nation, with hundreds of thousands of Sudanese refugees living in and around camps in eastern Chad.
Chad is a masculine given name of Anglo-Saxon/Welsh origins. It is the modernized form of the Old English given name Ceadda, possibly influenced by the Welsh word cad meaning "battle".
Ceadda was a 7th-century English saint.
Until the 20th century, Chad was very rarely used as a given name. According to the Social Security Administration, Chad first entered the top 1000 names for male children in the United States in 1945, when it was the 997th most popular name.
Its popularity suddenly peaked beginning in the mid 1960s, reaching rank 25 in 1972 and 1973.
From the mid 1970s, its popularity began a gradual decline, reaching rank 236 in 2000 and rank 667 as of 2013.
Goofy is the single father of a teenage boy named Max Goof in the town of Spoonerville, Ohio, though the two have a tense relationship. On the last day of school before summer vacation, Max and his best friends P.J. and Robert "Bobby" Zimmeruski hijack the auditorium stage in the middle of Principal Mazur's speech, creating a small concert where Max performs, while costumed as the pop singer Powerline. The performance succeeds in making Max a school celebrity and impressing his love interest, Roxanne; but he, P.J. and Bobby are sent to Mazur's office. Roxanne speaks with Max and agrees to go with him to a party where Powerline's concert will be aired live. However, Mazur exaggerates these events to Goofy and forewarns him that Max's actions may result in him facing capital punishment.

Years ago, California Institute of Technology professor Konstantin Batygin was inspired to embark on a journey of discovering what lurked beyond Neptune. What he and his collaborator discovered was a strange field of debris.
This field of debris exhibited a clustering of orbits, and something was keeping these orbits confined. The only plausible source would be the gravitational pull of an extra planet—Planet Nine.

Discovery of Eris Dwarf Planet
Eris was first observed on January 5, 2005, by a team of astronomers led by Mike Brown, Chad Trujillo, and David Rabinowitz.
The discovery was made using images taken in October 2003 with the 1.2-meter Samuel Oschin telescope at the Palomar Observatory in California, USA.
Eris is one of the largest known dwarf planets, and its discovery played a crucial role in reshaping our understanding of the outer solar system.
It orbits the Sun at an average distance of about 10 billion kilometers (6.2 billion miles) and takes approximately 557 years to complete one orbit.

8. What Is Eris?
Depending on your familiarity with our solar system, you may or may not know about Eris, and for good reason based on its location and how it relates to other planets and celestial objects in the system.
In short, Eris is one of the largest known dwarf planets in our solar system. For those who don't know, a Dwarf Planet is one that has the size and shape of a planet but fails to meet certain technical qualifications to be considered a full planet. Eris is about the same size as Pluto, but is three times farther from the Sun. Making it something on the very edges of our solar system. In fact, outside of some comets that have been discovered and a "unique object" from 2018, the two are the most distant known objects in our solar system.
Eris first appeared to be larger than Pluto. This triggered a debate in the scientific community that led to the International Astronomical Union's decision in 2006 to clarify the definition of a planet. Pluto, Eris and other similar objects are now classified as dwarf planets.
Originally designated 2003 UB313 (and nicknamed for the television warrior Xena by its discovery team), Eris is named for the ancient Greek goddess of discord and strife. The name fits since it remains at the center of a scientific debate about the definition of a planet.
7. The Discovery Of Eris
Given all we just told you, the discovery of this dwarf planet is really significant.
Eris was discovered by the team of Mike Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005, from images taken in October of 2003. The discovery was announced in July 2005, the same day as Makemake and two days after Haumea (two other dwarf planets), due in part to events that would later lead to controversy about Haumea. The search team had been systematically scanning for large outer Solar System bodies for several years, and had been involved in the discovery of several other large TNOs, including 50000 Quaoar, 90482 Orcus, and 90377 Sedna.
The reason that Eris wasn't discovered right away via the images in 2003 was very simple, Eris was moving so slowly that scientists weren't able to detect it. The team at the Palomar Observatory had automatic image-searching software that excluded all objects moving at less than 1.5 arcseconds per hour to reduce the number of false positives returned.
When Sedna was discovered in 2003, it was moving at 1.75 arcsec/h, and in light of that the team reanalyzed their old data with a lower limit on the angular motion, sorting through the previously excluded images by eye. In January 2005, the re-analysis revealed Eris's slow motion against the background stars. Thus leading to its true discovery.
After that, the team dedicated itself to learning more about the soon-to-be-named dwarf planet, mainly learning what kind of orbit it had, and eventually learning the discovery that it had a moon within its orbit.
6. The Xena Name
I'm sure some of you out there were a bit curious as to why a scientific team would nickname a planet "Xena" after the legendary TV show featuring Lucy Lawless. Granted, that's not the name the Dwarf Planet has now, but the story behind this nickname is honestly rather unique to our solar system.
Due to uncertainty over whether the object would be classified as a planet or a minor planet, because different nomenclature procedures apply to these different classes of objects (which would lead to the demoting of Pluto not long after Eris' discovery and classification), the decision on what to name the object had to wait until after the August 24, 2006 IAU ruling. As a result, for a time the object became known to the wider public as Xena.
But why that one? "Xena" was an informal name used internally by the discovery team. It was inspired by the title character of the television series Xena: Warrior Princess. The discovery team had reportedly saved the nickname "Xena" for the first body they discovered that was larger than Pluto. According to Mike Brown, who was part of the team that discovered the dwarf planet:
"We chose it since it started with an X (planet "X"), it sounds mythological (OK, so it's TV mythology, but Pluto is named after a cartoon, right?), and (this part is actually true) we've been working to get more female deities out there (e.g. Sedna).

KONSTANTIN BATYGIN:
Forbes named professor Konstantin Batygin the “next physics rock star” in its 2015 list of “30 Under 30: Young Scientists Who Are Changing the World.” He received his bachelor’s degree in physics from University of California, Santa Cruz in 2008, before pursuing graduate studies at California Institute of Technology. To date, Batygin has authored over seventy scientific publications, and his research has been featured on the pages of Nature as well as the front cover of Scientific American. In 2016, Batygin sparked international headlines with the announcement of the existence of an as-yet-unobserved ninth planet in the solar system. This discovery, conducted with research partner Mike Brown, fueled a worldwide race among astronomers to locate "Planet Nine.” Prior to joining the faculty at California Institute of Technology in 2014, Batygin was a postdoctoral scholar at Observatoire de la Côte d'Azur in Nice, France, and Harvard University. When not doing science, he moonlights as the lead singer and guitarist in the rock band, The Seventh Season.

TRANSCRIPT:
KONSTANTIN BATYGIN: The whole story dates back to about 2014-2015 when we started, me and my close collaborator Mike Brown, started looking into this problem. We were inspired by the work of some other researchers, Chad Trujillo and Scott Sheppard, who pointed out that something weird was happening in the distant solar system. That there was this weird clustering of a particular orbital parameter of asteroids beyond Neptune called The Argument of Perihelion. We thought what's going on there. We started looking more closely into what's going on and pretty quickly we realized that the field of debris, the field of icy debris beyond Neptune which is called the Kuiper belt in its most distant realms exhibits a remarkable clustering of orbits. It's as if somebody took these orbits and carefully arranged them all to all lie in the same plane that's about 20 degrees off the usual plane of the solar system and they're all kind of pointing I the same direction. So we thought why is that? That's a strange, strange pattern.
And through dynamical analysis basically by going to both the computer and writing down equations on the board we were able to demonstrate I think in a relatively straightforward manner that the only plausible explanation for why the distant solar system looks arranged is that there is a distant gravitational source, a distant gravitational pull which is keeping these orbits confined. And as far as we can see the only plausible source of such a gravitational pull is an extra planet. So that's kind of the beginnings of the Planet Nine hypothesis. Since that time we published our first paper back in 2016, so now four years ago. Since that time we've made additional progress and we've realized a number of interesting things that fit into this Planet Nine story that we didn't originally expect. For example, one of the things that theoretically should happen if Planet Nine is there is the distant orbits of the solar system, things that lie well beyond the orbit of Neptune should flip on their sides and then kind of pollute the inner solar system. By inner solar system I mean things interior to Neptune with objects that are highly, highly inclined. And it turns out such objects really are there.
And so there have been other kind of intriguing pieces of the puzzle that have sort of fallen all together since the publication of the original paper. And the latest on this story is that we've redone the analysis last year entirely with an updated data set that's become available since 2016. And we realized that the planet that we are searching for is a little bit smaller than we originally thought...

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Chadwick A. "Chad" Trujillo (born November 22, 1973) is an American astronomer, discoverer of minor planets and the co-discoverer of Eris, the most massive dwarf planet known in the Solar System.Trujillo works with computer software and has examined the orbits of the numerous trans-Neptunian objects (TNOs), which is the outer area of the Solar System that he specialized in. In late August 2005, it was announced that Trujillo, along with Michael Brown and David Rabinowitz, had discovered Eris in 2003. As a result of the discovery of the satellite Dysnomia, Eris was the first TNO known to be more massive than Pluto.

8. What Is Eris?
Depending on your familiarity with our solar system, you may or may not know about Eris, and for good reason based on its location and how it relates to other planets and celestial objects in the system.
In short, Eris is one of the largest known dwarf planets in our solar system. For those who don't know, a Dwarf Planet is one that has the size and shape of a planet but fails to meet certain technical qualifications to be considered a full planet. Eris is about the same size as Pluto, but is three times farther from the Sun. Making it something on the very edges of our solar system. In fact, outside of some comets that have been discovered and a "unique object" from 2018, the two are the most distant known objects in our solar system.
Eris first appeared to be larger than Pluto. This triggered a debate in the scientific community that led to the International Astronomical Union's decision in 2006 to clarify the definition of a planet. Pluto, Eris and other similar objects are now classified as dwarf planets.
Originally designated 2003 UB313 (and nicknamed for the television warrior Xena by its discovery team), Eris is named for the ancient Greek goddess of discord and strife. The name fits since it remains at the center of a scientific debate about the definition of a planet.
7. The Discovery Of Eris
Given all we just told you, the discovery of this dwarf planet is really significant.
Eris was discovered by the team of Mike Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005, from images taken in October of 2003. The discovery was announced in July 2005, the same day as Makemake and two days after Haumea (two other dwarf planets), due in part to events that would later lead to controversy about Haumea. The search team had been systematically scanning for large outer Solar System bodies for several years, and had been involved in the discovery of several other large TNOs, including 50000 Quaoar, 90482 Orcus, and 90377 Sedna.
The reason that Eris wasn't discovered right away via the images in 2003 was very simple, Eris was moving so slowly that scientists weren't able to detect it. The team at the Palomar Observatory had automatic image-searching software that excluded all objects moving at less than 1.5 arcseconds per hour to reduce the number of false positives returned.
When Sedna was discovered in 2003, it was moving at 1.75 arcsec/h, and in light of that the team reanalyzed their old data with a lower limit on the angular motion, sorting through the previously excluded images by eye. In January 2005, the re-analysis revealed Eris's slow motion against the background stars. Thus leading to its true discovery.
After that, the team dedicated itself to learning more about the soon-to-be-named dwarf planet, mainly learning what kind of orbit it had, and eventually learning the discovery that it had a moon within its orbit.
6. The Xena Name
I'm sure some of you out there were a bit curious as to why a scientific team would nickname a planet "Xena" after the legendary TV show featuring Lucy Lawless. Granted, that's not the name the Dwarf Planet has now, but the story behind this nickname is honestly rather unique to our solar system.
Due to uncertainty over whether the object would be classified as a planet or a minor planet, because different nomenclature procedures apply to these different classes of objects (which would lead to the demoting of Pluto not long after Eris' discovery and classification), the decision on what to name the object had to wait until after the August 24, 2006 IAU ruling. As a result, for a time the object became known to the wider public as Xena.
But why that one? "Xena" was an informal name used internally by the discovery team. It was inspired by the title character of the television series Xena: Warrior Princess. The discovery team had reportedly saved the nickname "Xena" for the first body they discovered that was larger than Pluto. According to Mike Brown, who was part of the team that discovered the dwarf planet:
"We chose it since it started with an X (planet "X"), it sounds mythological (OK, so it's TV mythology, but Pluto is named after a cartoon, right?), and (this part is actually true) we've been working to get more female deities out there (e.g. Sedna).

Years ago, California Institute of Technology professor Konstantin Batygin was inspired to embark on a journey of discovering what lurked beyond Neptune. What he and his collaborator discovered was a strange field of debris.
This field of debris exhibited a clustering of orbits, and something was keeping these orbits confined. The only plausible source would be the gravitational pull of an extra planet—Planet Nine.
While Planet Nine hasn't been found directly, the pieces of the puzzle are coming together. And Batygin is confident we'll return to a nine-planet solar system within the next decade.
----------------------------------------------------------------------------------
KONSTANTIN BATYGIN:
Forbes named professor Konstantin Batygin the “next physics rock star” in its 2015 list of “30 Under 30: Young Scientists Who Are Changing the World.” He received his bachelor’s degree in physics from University of California, Santa Cruz in 2008, before pursuing graduate studies at California Institute of Technology. To date, Batygin has authored over seventy scientific publications, and his research has been featured on the pages of Nature as well as the front cover of Scientific American. In 2016, Batygin sparked international headlines with the announcement of the existence of an as-yet-unobserved ninth planet in the solar system. This discovery, conducted with research partner Mike Brown, fueled a worldwide race among astronomers to locate "Planet Nine.” Prior to joining the faculty at California Institute of Technology in 2014, Batygin was a postdoctoral scholar at Observatoire de la Côte d'Azur in Nice, France, and Harvard University. When not doing science, he moonlights as the lead singer and guitarist in the rock band, The Seventh Season.

TRANSCRIPT:
KONSTANTIN BATYGIN: The whole story dates back to about 2014-2015 when we started, me and my close collaborator Mike Brown, started looking into this problem. We were inspired by the work of some other researchers, Chad Trujillo and Scott Sheppard, who pointed out that something weird was happening in the distant solar system. That there was this weird clustering of a particular orbital parameter of asteroids beyond Neptune called The Argument of Perihelion. We thought what's going on there. We started looking more closely into what's going on and pretty quickly we realized that the field of debris, the field of icy debris beyond Neptune which is called the Kuiper belt in its most distant realms exhibits a remarkable clustering of orbits. It's as if somebody took these orbits and carefully arranged them all to all lie in the same plane that's about 20 degrees off the usual plane of the solar system and they're all kind of pointing I the same direction. So we thought why is that? That's a strange, strange pattern.
And through dynamical analysis basically by going to both the computer and writing down equations on the board we were able to demonstrate I think in a relatively straightforward manner that the only plausible explanation for why the distant solar system looks arranged is that there is a distant gravitational source, a distant gravitational pull which is keeping these orbits confined. And as far as we can see the only plausible source of such a gravitational pull is an extra planet. So that's kind of the beginnings of the Planet Nine hypothesis. Since that time we published our first paper back in 2016, so now four years ago. Since that time we've made additional progress and we've realized a number of interesting things that fit into this Planet Nine story that we didn't originally expect. For example, one of the things that theoretically should happen if Planet Nine is there is the distant orbits of the solar system, things that lie well beyond the orbit of Neptune should flip on their sides and then kind of pollute the inner solar system. By inner solar system I mean things interior to Neptune with objects that are highly, highly inclined. And it turns out such objects really are there.
And so there have been other kind of intriguing pieces of the puzzle that have sort of fallen all together since the publication of the original paper. And the latest on this story is that we've redone the analysis last year entirely with an updated data set that's become available since 2016. And we realized that the planet that we are searching for is a little bit smaller than we originally thought...

Eris was first observed on January 5, 2005, by a team of astronomers led by Mike Brown, Chad Trujillo, and David Rabinowitz.
The discovery was made using images taken in October 2003 with the 1.2-meter Samuel Oschin telescope at the Palomar Observatory in California, USA.
Eris is one of the largest known dwarf planets, and its discovery played a crucial role in reshaping our understanding of the outer solar system.
It orbits the Sun at an average distance of about 10 billion kilometers (6.2 billion miles) and takes approximately 557 years to complete one orbit.

Solar System formation is an interesting thing. It's a like almost all the planets in our solar system are pointing toward super mysterious dwarf planet Eris. Is this Planet 9 related? Who knows bro. Ask Mike Brown Chad Trujillo or Scott Sheppard. They have more data on this subject than I or is this astrology? Or is it astronomy and astrology combined?
Planets have energy & power & gravity & reflect light and generate heat.
These are strange times.
God bless everyone,
