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.

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.

Trojan asteroid, any one of a number of asteroids that occupy a stable Lagrangian point in a planet’s orbit around the Sun. More than 7,000 Trojan asteroids are known in Jupiter’s orbit. Trojan asteroids have also been observed in the orbits of Earth, Mars, Uranus, and Neptune.

The Jupiter trojans are divided into two groups: The Greek camp in front of and the Trojan camp trailing behind Jupiter in their orbit. 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.

2021年10月4日 · Some of these leftover space rocks are pristine asteroids that now orbit with Jupiter in two huge swarms leading and trailing the planet. They’re known as the Trojan asteroids. They’re really mysterious and we think that they come from the outer solar system.

2020年3月5日 · Trojans, or Trojan Asteroids, are a large group of asteroids that share the orbit of planets around the Sun. The most famous and most numerous Trojans are the Jupiter Trojans. Trojans are usually small celestial bodies that share their orbit with larger heavenly bodies such as moons or planets.

The Trojan asteroids consist of the several hundred asteroids which are known to orbit the Sun at the distance of Jupiter. They travel in the vicinity of the two Lagrange points which are 60 degrees ahead of and behind Jupiter in orbit.

2021年10月21日 · Trojans are a special group of asteroids that can share orbit with a planet or larger body without risk of collision because of regions where there is gravitational stability. In the Solar System, there are regions with large concentrations of asteroids and comet-like objects.

A Trojan, in Astronomy, is a minor planet or moon that shares an orbit with a larger planet or satellite but does not collide with the larger planet because while it orbits, it stays safely in what is called as the Lagrangian points. In theory, there are also Trojan planets that may reside at …

2021年4月9日 · Trojan asteroids are in roughly circular orbits around the Sun at roughly the same distance as Jupiter, that are in 1:1 resonance with Jupiter and stay very roughly 60 degrees away from it. Scott Manley's video below shows two classes of asteroids in resonance with Jupiter.
