Asteroid 255 YU55 will pass between the earth and the moon on Tuesday. The object is the larger than an aircraft carrier and would cause significant damage if it struck either our planet or the moon.
Predictably, it has become the subject of internet rumors that its orbit has changed and that it might therefore hit the moon. There is not the slightest actual evidence that anything like this has happened. Dan Yeomans, the director of NASA’s Near Earth Object Program has said, "We’re extremely confident, 100 percent confident, that this is not a threat."
