Doomsday conspiracy theorists will only be disappointed on Tuesday as a space rock named "Asteroid 2005 YU55" will miss the Earth, but in space terms - just barely. The asteroid will pass between Earth and the orbit of the moon and as a result, will be 15% closer to our planet as it passes by than the moon.

Asteroid 2005 YU55 is expected to pass closest to Earth at a range of about 201,700 miles  on Tuesday at 4:28 p.m. MST. Asteroid 2005 YU55 is about the size of an aircraft carrier, spanning approximately 1,300 feet or 400 meters and is the largest space rock to have a close encounter with Earth in the last 35 years.

Sky watchers everywhere will be breaking out their telescopes for some star gazing fun Tuesday evening.
