NASA Says Asteroid Carrying Its Own Moon 'Flew By' Earth Yesterday

This is amazing!

At 11:19 EST on Monday, January 26th, planet Earth got a little hello from a nearby asteroid.

Asteroid 2004 BL86 has been followed by NASA for sometime, but this little space fly-by had a surprise: The asteroid came with a moon. 

Passing Earth from about 745,000 miles away, or 1.2 million kilometers, asteroid 2004 BL86 was filmed by the Deep Space Network antenna in Goldstone, California. 745,000 miles is about three times the distance between us and our own moon. The asteroid was 1,100 feet across, and its moon was 230 feet wide, according to NASA's press release

In the video above, 20 images are animated to show you what the passing asteroid and moon looked like. Truly amazing.
