An asteroid about the size of a school bus will pass close to Earth today, but it poses no danger to the planet, NASA astronomers say.
The huge rock, called Asteroid 2012 BX34, will close to within about 36,750 miles of Earth, or about .17 times the distance between the Earth and the moon, according to a Twitter post from Asteroid Watch, which is operated by NASA's Jet Propulsion Laboratory's Near Earth Object Office.
"It wouldn't get through our atmosphere intact even if it dared to try," an Asteroid Watch tweet says of the 37-foot diameter rock.
The asteroid makes its closest approach about 10:25 a.m. ET, according to NASA.
