Asteroid 2010 WC9 Lost and Found

Asteroid 2010 WC9 will safely pass at about half’s the moon’s distance on Tuesday, May 15, 2018. Estimates of its size range from 197 to 427 feet making the May 15 pass one of the closest approaches ever observed of an asteroid of this size. This asteroid was “lost” and then found again.

Asteroid 2010 WC9 is travelling through space at a speed of 28,655 miles per hour.
