The Jupiter trojans, commonly called trojan asteroids or simply trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each trojan librates around one of Jupiter's stable Lagrange points: either L 4, existing 60° ahead of the planet in its orbit, or L 5, 60° behind.
In astronomy, a trojan is a small celestial body (mostly asteroids) that shares the orbit of a larger body, remaining in a stable orbit approximately 60° ahead of or behind the main body near one of its Lagrangian points L 4 and L 5. Trojans can share the orbits of planets or of large moons. Trojans are one type of co-orbital object.
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.
The Trojan asteroids, which borrow their name from Greek mythology, orbit the sun in two swarms — one that’s ahead of Jupiter, the largest planet in our solar system, and a second one that ...
(706765) 2010 TK 7 (provisional designation 2010 TK 7) is a sub-kilometer Near-Earth asteroid and the first Earth trojan discovered; it precedes Earth in its orbit around the Sun. [4] [5] Trojan objects are most easily conceived as orbiting at a Lagrangian point, a dynamically stable location (where the combined gravitational force acts through ...
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 ...
(614689) 2020 XL 5 (provisional designation 2020 XL 5) is a near-Earth asteroid and Earth trojan discovered by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii on 12 December 2020. It oscillates around the Sun – Earth L 4 Lagrangian point (leading 60°), one of the dynamically stable locations where the combined gravitational force ...
Astronomers spotted a possible “sibling” planet that shares the orbit of another exoplanet in a system located 370 light-years away.
