What are the Trojan Asteroids? We Asked a NASA Scientist
What are the Trojan asteroids? These mysterious space rocks have been gravitationally trapped in Jupiter’s orbit around the Sun for billions of years and hold clues to the formation of our solar system. NASA’s Lucy mission will be the first spacecraft to study these ancient relics up close. Scientist Audrey Martin at Northern Arizona University has the details.

Lucy Mission Overview: Journey to Explore the Trojan Asteroids
Launching in late 2021, Lucy will be the first space mission to explore the Trojan asteroids. These are a population of small bodies that are left over from the formation of the solar system. They lead or follow Jupiter in their orbit around the Sun, and may tell us about the origins of organic materials on Earth.
Lucy will fly by and carry out remote sensing on six different Trojan asteroids and will study surface geology, surface color and composition, asteroid interiors/bulk properties, and will look at the satellites and rings of the Trojans.

Studying Trojan Asteroids With Lucy
NASA’s Lucy mission is launching in 2021 and will fly by seven different Trojan asteroids that are orbiting the same distance from the Sun as Jupiter. This video highlights the four main science objectives and the instruments aboard the spacecraft that will be utilized. Lucy will be the first space mission to study the Trojan asteroids, which are remnants of our early solar system.

Jupiter's Trojan Asteroids
This is a view of the inner solar system in a Jupiter-rotating reference frame. The camera begins at viewpoint oblique to the ecliptic plane, then moves up to a top-down view. Clusters of Trojan asteroids appear behind and ahead of Jupiter in its orbit.
Read more: https://www..nasa.gov/feature/goddard/2021/how-were-the-trojan-asteroids-discovered-and-named
Jupiter's swarms of Trojan asteroids may be remnants of the primordial material that formed the outer planets, and serve as time capsules from the birth of our Solar System more than 4 billion years ago. The Trojans orbit in two loose groups that orbit the Sun, with one group always ahead of Jupiter in its path, the other always behind. At these two Lagrange points the bodies are stabilized by the Sun and Jupiter in a gravitational bal...

How does a Trojan asteroid share Earth's orbit?
Paul Wiegert, an astronomy professor from The University of Western Ontario, answers the question: "How does a Trojan asteroid share Earth's orbit?"
Studying images compiled by NASA, an astronomer from The University of Western Ontario has proved the existence of the first Trojan asteroid found to share Earth's orbit. The findings of Paul Wiegert and his colleagues at Athabasca University and the Canada-France-Hawaii Telescope were featured as the cover story for the July 28 issue of distinguished journal, Nature.

Searching for Earth’s Trojan Asteroids
Trojan asteroids are common at the L4 and L5 Lagrange points of other planets, leading or following the planet in its orbit. But detecting our own Trojan asteroids from Earth is difficult since they appear close to the sun from our perspective. In mid-February 2017, NASA's OSIRS-REx mission will search for these elusive objects when the spacecraft passes by Earth's L4 Lagrange point, en route to asteroid Bennu in 2018. Jim Green, the Director of Planetary Science at NASA, discusses OSIRIS-REx and its search for Earth's Trojan asteroids.

This is a view of the inner solar system in a Jupiter-rotating reference frame. The camera begins at viewpoint oblique to the ecliptic plane, then moves up to a top-down view. Clusters of Trojan asteroids appear behind and ahead of Jupiter in its orbit.
Read more: https://www..nasa.gov/feature/goddard/2021/how-were-the-trojan-asteroids-discovered-and-named
Jupiter's swarms of Trojan asteroids may be remnants of the primordial material that formed the outer planets, and serve as time capsules from the birth of our Solar System more than 4 billion years ago. The Trojans orbit in two loose groups that orbit the Sun, with one group always ahead of Jupiter in its path, the other always behind. At these two Lagrange points the bodies are stabilized by the Sun and Jupiter in a gravitational balancing act. These primitive bodies hold vital clues to deciphering the history of the solar system, and perhaps even the origins of life and organic material on Earth.
Lucy will be the first space mission to study the Trojans. The mission takes its name from the fossilized human ancestor (called “Lucy” by her discoverers) whose skeleton provided unique insight into humanity's evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the formation of the solar system.
Lucy will launch in October 2021 and, with boosts from Earth's gravity, will complete a 12-year journey to seven different asteroids — a Main Belt asteroid and six Trojans, the last two members of a “two-for-the-price-of-one” binary system. Lucy’s complex path will take it to both clusters of Trojans and give us our first close-up view of all three major types of bodies in the swarms (so-called C-, P- and D-types).

Trojan asteroids are common at the L4 and L5 Lagrange points of other planets, leading or following the planet in its orbit. But detecting our own Trojan asteroids from Earth is difficult since they appear close to the sun from our perspective. In mid-February 2017, NASA's OSIRS-REx mission will search for these elusive objects when the spacecraft passes by Earth's L4 Lagrange point, en route to asteroid Bennu in 2018. Jim Green, the Director of Planetary Science at NASA, discusses OSIRIS-REx and its search for Earth's Trojan asteroids.

SECOND EARTH TROJAN ASTEROID DISCOVERED
Imagine being an amateur astronomer and discovering an object that turns out to be gravitationally connected with our planet Earth. Amateur astronomer Tony Dunn has reported there is a second Trojan asteroid sharing the Earth's orbit.

What's a Trojan? But what type of object is it? Does every planet have its own Trojans?
In astronomy, a rojan is a small celestial body, most of the times it is an asteroid, that shares the orbit of a larger one, remaining in a stable orbit approximately 60° ahead or behind the main body near one of the so-called “Lagrange points”.
Trojans can share the orbits of planets or of large moons.
The term "trojan" originally referred to the "trojan asteroids" (Jovian trojans) that orbit close to the Lagrangian points of Jupiter. These have long been named for figures from the Trojan War of Greek mythology. By convention, the asteroids orbiting near the L4 point of Jupiter are named for the characters from the Greek side of the war, whereas those orbiting near the L5 of Jupiter are from the Trojan side. (we find, for example, 588
Achilles and 1172 Äneas!)
How big is a Trojan, and what it's made of?
Like other asteroids, Trojan are space rocks.
We know some asteroids are as small as boulders. Others are as big as football fields. Some asteroids are almost as large as planets, and astronomers sometimes argue about whether really big asteroids ought to be called planets or not.
Asteroids are made of rock, metals and other elements. Some even contain water, astronomers say. Asteroids that are mostly stone sometimes are more like loose piles of rubble. Asteroids that are mostly iron are more, well, rock-solid.
Meteorites found on Earth often come from asteroids, and so they help astronomers figure out what's in asteroids. An iron meteorite can be 91 per cent iron and 8.5 per cent nickel and might also contain cobalt. A stony meteorite can contain oxygen, silicon, magnesium, calcium and other elements.
Most Jupiter Trojans are D-class asteroids, which predominate in the outer regions of the asteroid belt. Very few have been classified as P or C-type asteroids.
Water hasn’t yet been detected on any of them; however, there is a possibility that some of them might contain it. Recent studies suggest that the Jupiter Trojans resemble comets or Kuiper Belt objects when it comes to their composition, mainly water-ice with a layer of dust; however, observations continue.
So, what was Tony Dunn discovery? And why it was so important?
Earth Trojans are hard to find because, during most of their orbits, they appear close to the Sun in the sky.
What about the first Earth Trojan? When was it discovered?
We are going to end this video, but first...here's a bunch of “Did you know that”... we collected for you!
Did you know that...
The second-largest Jupiter Trojan is 617 Patroclus. It has a diameter of 140 km / 86.9 mi.
The asteroid with the highest albedo of the Jupiter Trojans, and all known Trojans, is 4709 Ennomos – having an albedo of 0.18. This high albedo may indicate the presence of water-ice.
