Scientist say an asteroid the size of a city block will whiz very near Earth tonight — within about one-fourth of the distance to the moon.
The space rock, called asteroid 2012 TC4, is about 56 feet wide, but NASA says it poses no danger of impacting Earth, Space.com reports. Likely, you won't be able to see it with the naked eye, according to Tellus Science Museum in Cartersville.
"There is a 100-foot diameter asteroid passing the Earth tonight at 12:30 a.m. (Friday morning) at a distance of about 59,000 miles," officials said in a statement. "The media is saying it is visible, but it's at 13.7 magnitude, that’s about 1,500 times fainter than you can see with the unaided eye.
"Our telescope could see it but it would be a very faint dot at best. So look south around midnight and you will see...nothing."
