NASA has given its standard warning that while this is a little close for comfort there is nothing to fear. Asteroid DX110 is a 100-foot long space rock that will pass the Earth at a distance so close that it will actually be closer than the moon. While current predicted trajectories indicate that DX110 poses no danger to the Earth, possibly the most frightening thing about it is how the asteroid was discovered. DX110 was identified just five days before its flyby on February 28, 2014.
While DX110 isn’t expected to be a catastrophic event, it’s easy to see why this is worrisome. If an asteroid could pass this close and have been so close to going completely undetected, what are the odds that a similar asteroid on a direct trajectory with an Earth collision could also slip through scientists’ nets?
