Tags: Planet.

2011 CQ1 is a meteoroid discovered on February 4 2011 by Richard A. Kowalski at the Catalina Sky Survey. On the same day the meteoroid passed within 0.85 Earth radii (5480 kilometers (3410 mi)) of Earth’s surface and was perturbed from the Apollo class to the Aten class of near-Earth objects. With a relative velocity of only 9.7 km/s had the asteroid passed less than 0.5 Earth radii from Earth’s surface it would have fallen as a brilliant fireball.
