An Earth trojan is an asteroid that orbits the Sun in the vicinity of the Earth–Sun Lagrange points L 4 (leading 60°) or L 5 (trailing 60°), thus having an orbit similar to Earth's. Only two Earth trojans have so far been discovered.
Asteroids in the leading (L 4) orbit are named after Greek heroes (the "Greek node or camp" or "Achilles group"), and those at the trailing (L 5) orbit are named after the heroes of Troy (the "Trojan node or camp"). [2] The asteroids 617 Patroclus and 624 Hektor were named before the Greece/Troy rule was devised, resulting in a "Greek spy ...
Asteroids in the L 4 and L 5 Sun–Mars Lagrangian points are sometimes called Mars trojans, with a lower-case t, as "Trojan asteroid" was originally defined as a term for Lagrangian asteroids of Jupiter. They may also be called Mars Lagrangian asteroids.
NASA has blasted a spacecraft, traveling at speeds up to 92,000 mph, to the most mysterious asteroids in our solar system.Called the Trojan asteroids, they are trapped in two swarms — one in ...
This is a list of Jupiter trojans that lie in the Trojan camp, an elongated curved region around the trailing L 5 Lagrangian point, 60° behind Jupiter in its orbit.. All the asteroids at the trailing L 5 point have names corresponding to participants on the Trojan side of the Trojan War, except for 617 Patroclus, which was named before this naming convention was instituted.
In some ways these asteroids look similar to the near-Earth asteroid ... including a close encounter with another main belt asteroid called Donaldjohanson in 2025. ... There are about 7,000 Trojan ...
Astronomers spotted a possible “sibling” planet that shares the orbit of another exoplanet in a system located 370 light-years away.
2010 TK 7 was at the near-Earth end of its tadpole in 2010–2011, [4] which facilitated its discovery. 2010 TK 7 's orbit has a chaotic character, making long-range predictions difficult. Prior to 500 AD, it may have been oscillating about the L 5 Lagrangian point (60 degrees behind Earth), before jumping to L 4 via L 3 .
