Kleopatra gave birth to twins … moons

Kleopatra, a dog-bone shaped asteroid named after the last pharaoh of ancient Egypt, is a pile of rubble that spawned twin moons about 100 million years ago, astronomers announced in a new study.

The discovery stems from detailed observations of 135-mile-long Kleopatra with the Keck II telescope in Hawaii made in 2008 that confirmed the asteroid’s dog-bone shape and the presence of two moons, each about 5 miles wide.
