Observations of binary asteroid 2000 DP107
2000 DP107 was the first asteroid discovered by radar to be a binary. It was observed in both October 2000 and September 2008. The data show that it is composed of an ~800 meter diameter primary and a ~300 meter diameter secondary revolving around their common center of mass. The primary rotates much faster than the secondary.

These and more observations were used to develop a shape model for the primary:
