The 250 meter (919 foot) asteroid 2007 TU24 passed Earth on Tuesday, January 29, but it didn’t come close enough to pose danger. It was small enough that very few people would even be able to see it, but large enough that if it had hit Earth, it would be seriously worrisome. For more information, see the Astronomy Picture of the Day for January 30.
