A huge asteroid set to sail past Earth on Friday has its own moon, NASA scientists have just discovered.

Researchers obtained a series of radar images of the approaching asteroid 1998 QE2 late Wednesday (May 29) using the Deep Space Network antenna at Goldstone, Calif. Images captured over the course of two hours showed that the asteroid is actually a binary system.
