An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An asteroid family is a more specific term than asteroid group whose members, while sharing some broad ...

Lucy (spacecraft) Lucy. (spacecraft) Lucy is a NASA space probe on a twelve-year journey to eight different asteroids. It is slated to visit two main belt asteroids as well as six Jupiter trojans – asteroids that share Jupiter 's orbit around the Sun, orbiting either ahead of or behind the planet.
An Earth trojan is an asteroid that orbits the Sun in the vicinity of the Earth –Sun Lagrangian 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 name "trojan" was first used in 1906 for the Jupiter trojans, the asteroids that were observed near ...
