Koronis family
From Wikipedia, the free encyclopedia
The Koronis family is a family of asteroids in the Main Belt between Mars and Jupiter. They are thought to have have been formed at least two billion years ago in a catastrophic collision between two larger bodies. All are between 20 - 40 km (12 to 26 miles) in diameter and travel in a cluster along the same orbit.[1]
On August 28, 1993, the Galileo spacecraft visited a member of this family, 243 Ida.
