A fairly big Asteroid will pass by Earth early Sunday morning (April 1), however, it is not expected to pose a problem of any kind:

Interesting that it will supposedly be closer to Earth than the moon is to Earth. Probably no chance of seeing it in our area though, if that were even possible, as we have had cloudy, rainy, and stormy weather all afternoon here.
This Asteroid is supposed to be the size of an airplane !!! Wow!!
