Earth got a close encounter Monday as an asteroid as big as three football fields whizzes by at 27,000 mph.

The asteroid wasn't a threat it missed the Earth by 2 million miles. Dubbed 2000 EM26, it's about 885 feet in diameter

The asteroid began its close pass monitored by Slooh, a robotic telescope service on Mount Teide in the Canary Islands.

Asteroids are small rocky planetoids that revolve around the sun but are too small to be considered planets.

2000 EM26 was discovered March 5, 2000. You can see a diagram of its orbit from NASA's Jet Propulsion Laboratoryhere.

The asteroid's passage comes a year and two days after an asteroid ripped through the skies over Chelyabinsk, Russia. That asteroid damaged thousands of buildings and was felt over a very wide area. It was about 65 feet across.
