EarthSky says estimates of its size range from 197 to 427 feet (60-130 meters), making the May 15 pass one of the closest approaches ever observed of an asteroid of this size.
This asteroid was “lost” and then found again as it was first detected in November 30th, 2010.
Astronomers watched it until December 10th when it then became to faint to see.
In May of this year, astronomers realized it was following the orbit of asteroid 2010 WC9.
The pass-by will happen around 6:05 tonight (Atlantic time).
The asteroid will be 0.53 lunar-distances from Earth (126,419 miles or 203,453 km from Earth).
According to orbit calculations made by NASA’s Jet Propulsion Laboratory, the May 15 close approach is the closest of this particular asteroid in nearly 300 years.
We know it’s not going to hit, but if it were and human-kind was to go extinct, what would you do with your final hours?
