List of minor-planet groups

(重定向自Asteroid group)
Asteroid groups out to the orbit of Jupiter. The asteroid belt is shown in red

A minor-planet group is a population of minor planets that have a share broadly similar orbits. Members are generally unrelated to each other, unlike in an asteroid family, which often results from the break-up of a single asteroid. It is customary to name a group of asteroids after the first member of that group to be discovered, which is often the largest.
