Asteroid 2005 YU55 Makes Closest Pass To Earth Today

Don't look now -- if you did you wouldn't see anything -- but the asteroid 2005 YU55 is expected to make its closest approach to Earth today at 6:28 p.m. ET.

It will still be far away -- about 201,700 miles from our little blue planet, which is a little less than 8,000 miles in diameter. That's closer than the moon's orbit (239,000 miles on average), but NASA says emphatically that the asteroid will miss us. It has been tracking it, like thousands of other so-called Near-Earth Objects, since it was first spotted six years ago, and its path is well known.
