“In fact, some of these orbit paths actually approach Earth, coming just a little farther or a little closer than the Moon’s distance.
“It is these objects, especially the larger ones, that we closely observe and track.”
NASA’s Center for Near Earth Object Studies (CNEOS) first spotted Asteroid WR3 on November 27 this year.
As of December 1, the space agency has observed the space rock 74 times to determine its size, speed and trajectory.
NASA determined the asteroid measures somewhere in the range of 249ft to 55.7ft (76m to 170m) in diameter.
