Its size ranges from 197 to 427 feet (60-130 meters), making it possible to pass the closest ever on May 15.
Nearly eight years later, astronomers realized that an asteroid they temporarily called ZJ99C60 was actually 2010 WC9 returning. But it was not imaged again until May 8th, 2018, when it was temporarily called ZJ99C60, and then again on May 10 when experts were able to identify it as 2010 WC9.
Astronomers have rediscovered a "lost" asteroid just a few days before it makes a close pass by Earth. After it was recently reported that our planet will be hit by an asteroid so big that it will wipe out most forms of life, NASA's Jet Propulsion Laboratory has now reported that a massive asteroid will have a near-Earth encounter on May 15.
Although 2010 WC9 is hurtling towards us at an incredible speed of 28,655 miles per hour (46,116 km/h), it's unlikely that the asteroid will change its trajectory. In accordance with the received reports, this flyby is predicted to take place at near about 3.05 p.m. Now, imagine the damage that could be done by an asteroid the size of a house entering the atmosphere at more than 45,000 km/h.

A small private funeral will be held "in the coming days" and a memorial service "open to all" at a later date. Tessa Jowell once said she'd "jump under a bus" for Tony Blair.
The Cheliabinsk meteorite measured no more than 20 meters when it entered the atmosphere over Russian Federation in February 2013. For those hoping to catch a glimpse of the asteroid, it will be visible with a telescope for some people.
"We have discussed unusual objects 2010 with WC9 with EarthSky!". Viewers can also watch a live broadcast of the zooming asteroid on Northolt Branch Observatories' Facebook page on May 14. Astronomers believe, however, that despite its larger size and the distance from our planet, it doesn't pose danger and is likely going to just fly by.
"The broadcast will be less than 25 minutes in duration, as the asteroid will cross our field of view within that period of time", he added.
"The asteroid will be moving quite rapidly (30 arc seconds per minute)".
