Binary asteroid

From Free net encyclopedia

The term binary asteroid refers to a system in which two asteroids orbit their common centre of gravity, in analogy with binary stars.

Asteroids that have moons of roughly the same size are sometimes called "double asteroids". An example is the 90 Antiope system.

For more detail, see the entry on asteroid moons.
