An asteroid named 2007 TU24, discovered on October 11, 2007 will approach Earth to as close as 334,000 miles. It’s diameter is between 50 and 200 feet (150 – 600 meters) and its closest approach is expected to be Jan 29 – Jan 30. There is no chance it will collide with Earth as it will be 50% further from Earth than the moon.

An object this size comes this close to Earth about once every five years, with impacts expected once every 37,000 years. The next time a near earth object of this size gets this close will be in 2027.
