Aten asteroid
The Aten asteroids are a group of near-Earth asteroids, named after the first of the group, 2062 Aten, discovered by Eleanor F. Helin on January 7, 1976. As of August 2015, there are 937 known Atens, of which more than a hundred are classified as potentially hazardous asteroids.
Aten asteroids are defined by having a semi-major axis of less than one astronomical unit (AU), the distance from the Earth to the Sun. They also have an aphelion (furthest distance from the Sun) greater than 0.983 AU. Asteroids' orbits can be highly eccentric. An Aten orbit need not be entirely contained within Earth's orbit, as nearly all known Aten asteroids have their aphelion greater than 1 AU although their semi-major axis is less than 1 AU. Observation of objects inferior to the Earth's orbit is difficult and this difficulty may be the cause of some sampling bias in the apparent preponderance of eccentric Atens. Aten asteroids account for only about 6% of the known near-Earth asteroid population. Many more Apollo-class asteroids are known than Aten-class asteroids, possibly because of the sampling bias.

Apophis Asteroid Hitting Earth In 2029 | Secrets of Space
Seven years from today – on Friday, April 13, 2029, Apophis Asteroid will Hit Earth In 2029 a relatively large and extremely infamous asteroid named Apophis will zoom past Earth. It’ll be easily visible to the eye. Many astronomers will study it. But Apophis will not strike us in 2029. For a time, initial observations of this asteroid suggested that – if, at the 2029 pass, Apophis passed through a region of space only half a mile wide, dubbed a “keyhole” by astronomers, then it might strike us exactly seven years later on April 13, 2036. But, by 2006, that idea had also been disproven. Astronomers at Kitt Peak National Observatory near Tuscon, Arizona, discovered Apophis on the evening of June 19, 2004. The team were searching for asteroids low in the western sky. They were specifically l...

SUMMARY
=======
The Aten asteroids are a dynamical group of asteroids whose orbits bring them into proximity with Earth. By definition, Atens are Earth-crossing asteroids (a 1.0 AU and Q 0.983 AU). The group is named after 2062 Aten, the first of its kind, discovered by American astronomer Eleanor Helin at Palomar Observatory on 7 January 1976. Since then, more than 1,300 Atens have been discovered, of which many are classified as potentially hazardous asteroids.

Seven years from today – on Friday, April 13, 2029, Apophis Asteroid will Hit Earth In 2029 a relatively large and extremely infamous asteroid named Apophis will zoom past Earth. It’ll be easily visible to the eye. Many astronomers will study it. But Apophis will not strike us in 2029. For a time, initial observations of this asteroid suggested that – if, at the 2029 pass, Apophis passed through a region of space only half a mile wide, dubbed a “keyhole” by astronomers, then it might strike us exactly seven years later on April 13, 2036. But, by 2006, that idea had also been disproven.
Astronomers at Kitt Peak National Observatory near Tuscon, Arizona, discovered Apophis on the evening of June 19, 2004. The team were searching for asteroids low in the western sky. They were specifically looking for objects in the direction of the sun. The asteroid they found was originally designated 2004 MN4. It was 57 degrees from the sun, unusually close for an asteroid.
But astronomers quickly recognized this asteroid was different from most. It orbits the sun in less than one Earth-year (Apophis takes 323.6 days to orbit the sun. Earth takes 365.3 days). And Apophis gets nearly as close to the sun as the planet Venus, then heads out to just beyond Earth’s orbit. Its orbit defines Apophis as what astronomers call an Aten-class asteroid.
Apophis is a space rock about 1,000 feet (340 meters) across. Calculations in recent years have proven the asteroid will safely glide past Earth in both 2029 and 2036. In 2029, Apophis should pass at a nominal distance of 19,662 miles (31,643 km) from the Earth’s surface. That’s in contrast to the moon’s average distance of about 250,000 miles (380,000 km). And it’s closer than many Earth-orbiting satellites. As the asteroid encounters Earth’s gravitational field in 2029, one result could be asteroid-quakes on Apophis. This passage will also change the orbit of Apophis slightly.
Apophis made a [close approach in 2013] with Earth, it was still nearly 10.6 million miles (17 million kilometers) away. Even so, we were able to acquire incredibly precise information about its distance to an accuracy of about 490 feet (150 meters).
Later calculations let NASA scientists announce on March 26, 2021, that Earth is safe from an impact with the relatively large asteroid for at least the next 100 years. Radar observations taken at NASA’s Goldstone Deep Space Communications Complex in California and the Green Bank Observatory in West Virginia have officially ruled out an impact in 2068, the only year out of the next 100, that previously showed a slight risk. Earlier observations had ruled out impacts during the upcoming 2029 and 2036 flybys.
This new analysis means that Apophis is no longer on the Sentry Impact Risk Table, which is a list of objects that pass so close by Earth that astronomers have not yet been able to rule out a possible strike.
This campaign not only helped us rule out any impact risk, but it also set us up for a wonderful science opportunity in 2029.
Astronomers in Hawaii studied how Yarkovsky acceleration, or pushes due to sunlight, would change Apophis’ orbit. In some instances, acceleration – a change in an object’s speed and direction through space – can help avoid a collision. Studies of Yarkovsky acceleration as related to asteroid Apophis suggest this is the case for this asteroid.
Astronomer Dave Tholen and colleagues suggest that Apophis is drifting more than 500 feet (about 170 meters) per year from its expected position in its orbit. These observations aren’t easy to obtain and analyze. Factors such as the asteroid’s distance at the time of observation, its composition, its shape, and its surface features all affect the outcome.
Apophis is now in a part of the sky that is not observable from Earth. It will remain so until we see it again in 2029.

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
=======
The Aten asteroids are a dynamical group of asteroids whose orbits bring them into proximity with Earth. By definition, Atens are Earth-crossing asteroids (a 1.0 AU and Q 0.983 AU). The group is named after 2062 Aten, the first of its kind, discovered by American astronomer Eleanor Helin at Palomar Observatory on 7 January 1976. Since then, more than 1,300 Atens have been discovered, of which many are classified as potentially hazardous asteroids.

NASA Warns of Massive and Gigantic Asteroid Hurtling Towards Earth!
NASA has issued a warning about a massive asteroid hurtling towards Earth at a breakneck speed of 62,723 km/hour (38974 Miles per hour). The asteroid, known as 2006 HV5, is set to pass perilously close to our planet on April 26th, 2023, at a distance of 2.4 million kilometers(Approximately 1.4 million miles).
Belonging to the potentially hazardous Aten group of asteroids, this colossal force serves as a reminder of the dangers of the cosmos and the importance of organizations like NASA in keeping us safe.

Asteroids are characterized based on orbit, size and composition.
Apollo - Earth crossing Near Earth Asteroid (NEA) with semi-major axis larger than the Earth's
Amor - Earth approaching asteroid with orbits outside of Earth but inside the orbit of Mars
Aten - Earth crossing asteroid with semi-major axis smaller than Earth's
Atira - Orbit is contained inside of Earth's orbit
Determining the Size of an Asteroid
Radar - Radio waves emitted from large antennas bounce off an asteroid and are reflected back.
Infrared Light - Infrared is more accurate than visible light because a small highly reflective asteroid can look the same size as larger less reflective asteroids.
SMASS Classification of asteroid types are based on color and spectral shape
C-Group are made up mostly of carbon and comprise 75% of known asteroids.
S-Group are made up mostly of silicates, 17% of known asteroids.
X-Group are metallic asteroid.
D-Type asteroids are composed of organic rich silicates, carbon and possibly water ice and are found orbiting the outer asteroid belt and further.
V-Type asteroids are large asteroids similar to Vesta and make up about 6% of the main belt.
Additional types include T, Ld and O

Seven years from today – on Friday, April 13, 2029, Apophis Asteroid will Hit Earth In 2029 a relatively large and extremely infamous asteroid named Apophis will zoom past Earth. It’ll be easily visible to the eye. Many astronomers will study it. But Apophis will not strike us in 2029. For a time, initial observations of this asteroid suggested that – if, at the 2029 pass, Apophis passed through a region of space only half a mile wide, dubbed a “keyhole” by astronomers, then it might strike us exactly seven years later on April 13, 2036. But, by 2006, that idea had also been disproven.
Astronomers at Kitt Peak National Observatory near Tuscon, Arizona, discovered Apophis on the evening of June 19, 2004. The team were searching for asteroids low in the western sky. They were specifically looking for objects in the direction of the sun. The asteroid they found was originally designated 2004 MN4. It was 57 degrees from the sun, unusually close for an asteroid.
But astronomers quickly recognized this asteroid was different from most. It orbits the sun in less than one Earth-year (Apophis takes 323.6 days to orbit the sun. Earth takes 365.3 days). And Apophis gets nearly as close to the sun as the planet Venus, then heads out to just beyond Earth’s orbit. Its orbit defines Apophis as what astronomers call an Aten-class asteroid.
Apophis is a space rock about 1,000 feet (340 meters) across. Calculations in recent years have proven the asteroid will safely glide past Earth in both 2029 and 2036. In 2029, Apophis should pass at a nominal distance of 19,662 miles (31,643 km) from the Earth’s surface. That’s in contrast to the moon’s average distance of about 250,000 miles (380,000 km). And it’s closer than many Earth-orbiting satellites. As the asteroid encounters Earth’s gravitational field in 2029, one result could be asteroid-quakes on Apophis. This passage will also change the orbit of Apophis slightly.
Apophis made a [close approach in 2013] with Earth, it was still nearly 10.6 million miles (17 million kilometers) away. Even so, we were able to acquire incredibly precise information about its distance to an accuracy of about 490 feet (150 meters).
Later calculations let NASA scientists announce on March 26, 2021, that Earth is safe from an impact with the relatively large asteroid for at least the next 100 years. Radar observations taken at NASA’s Goldstone Deep Space Communications Complex in California and the Green Bank Observatory in West Virginia have officially ruled out an impact in 2068, the only year out of the next 100, that previously showed a slight risk. Earlier observations had ruled out impacts during the upcoming 2029 and 2036 flybys.
This new analysis means that Apophis is no longer on the Sentry Impact Risk Table, which is a list of objects that pass so close by Earth that astronomers have not yet been able to rule out a possible strike.
This campaign not only helped us rule out any impact risk, but it also set us up for a wonderful science opportunity in 2029.
Astronomers in Hawaii studied how Yarkovsky acceleration, or pushes due to sunlight, would change Apophis’ orbit. In some instances, acceleration – a change in an object’s speed and direction through space – can help avoid a collision. Studies of Yarkovsky acceleration as related to asteroid Apophis suggest this is the case for this asteroid.
Astronomer Dave Tholen and colleagues suggest that Apophis is drifting more than 500 feet (about 170 meters) per year from its expected position in its orbit. These observations aren’t easy to obtain and analyze. Factors such as the asteroid’s distance at the time of observation, its composition, its shape, and its surface features all affect the outcome.
Apophis is now in a part of the sky that is not observable from Earth. It will remain so until we see it again in 2029.

Aten asteroid
The Aten asteroids are a group of near-Earth asteroids, named after the first of the group, 2062 Aten, discovered by Eleanor F. Helin on January 7, 1976. As of August 2015, there are 937 known Atens, of which more than a hundred are classified as potentially hazardous asteroids.
Aten asteroids are defined by having a semi-major axis of less than one astronomical unit (AU), the distance from the Earth to the Sun. They also have an aphelion (furthest distance from the Sun) greater than 0.983 AU. Asteroids' orbits can be highly eccentric. An Aten orbit need not be entirely contained within Earth's orbit, as nearly all known Aten asteroids have their aphelion greater than 1 AU although their semi-major axis is less than 1 AU. Observation of objects inferior to the Earth's orbit is difficult and this difficulty may be the cause of some sampling bias in the apparent preponderance of eccentric Atens. Aten asteroids account for only about 6% of the known near-Earth asteroid population. Many more Apollo-class asteroids are known than Aten-class asteroids, possibly because of the sampling bias.
