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.
Astronomers estimate that the Jovian trojans are about as numerous as the asteroids of the asteroid belt. [6] Later on, objects were found orbiting near the Lagrangian points of Neptune, Mars, Earth, [7] Uranus, and Venus. Minor planets at the Lagrangian points of planets other than Jupiter may be called Lagrangian minor planets. [8]
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.
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 ...

Four large asteroids will make their closest approaches to Earth on Thursday, each passing by the planet within a 24-hour time frame. Two had already zipped past early in the morning, according to ...
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 ...
(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 ...
