What is a Trojan asteroid?

AstronomySmall Bodies

Quick Answer

A Trojan asteroid is a small body that shares an orbit with a planet, usually clustered near stable Lagrange points. Jupiter has the most famous Trojan swarms.

The Full Story

Trojan asteroids orbit the Sun in the same path as a planet, but they stay near one of the planet’s stable gravitational neighborhoods, commonly the L4 and L5 Lagrange points. These regions are about 60 degrees ahead of or behind the planet in its orbit. Jupiter has the largest known Trojan population, but other planets, including Earth and Neptune, also have Trojans. Their stable arrangement makes them important clues to the early history of planetary migration and Solar System formation.
