2010 AL30 is an approximately 10–15 meter large asteroid that passed Earth on January 13, 2010 at approximately 13:46 CET at a distance of approximately 130,000 km. The asteroid moves at about 36,000 km / h and belongs to the class of Apollo asteroids, which cross the earth's orbit .
The asteroid was discovered by the Lincoln Laboratories LINEAR Survey at MIT on January 10, 2010 and is certain not to collide with Earth. The object needs almost exactly one year to orbit the sun , which sparked speculation that it could be a rocket stage that was ejected or something similar. However, this representation was rejected by NASA .
