Don't worry though that it is still very far away from us and scientist don't think there is any danger of it reaching Earth. Nearly eight years later, employees of the Observatory again managed to capture the asteroid.
The asteroid is said to be traveling at 28,655 miles per hour, Earthsky said.
The asteroid of 18 magnitudes is fainting and now at +15 mag. Experts suggest it might get as bright as +11 mag when it closely passes from the Earth.
However, this time, it's about a different space rock.
"Asteroids this size approach about this close about once every decade or so, on average", Chodas said. When compared to other asteroids that have zipped by the Earth, 2010 WC9 is not a large one, although it's larger compared to the Chelyabinsk meteor, that was 65 feet long.
While the asteroid will be fairly close to Earth, the 200-400-foot rock won't be close enough to be seen by the naked eye.
According to Fox News, 2010 WC9 was first spotted in November 2010 by the NASA-backed space project Catalina Sky Survey, but was then lost for several years, only to be rediscovered on May 8. The object was first designated as ZJ99C60, but soon it was confirmed it was the lost asteroid 2010 WC9. Viewers can also watch a live broadcast of the zooming asteroid on Northolt Branch Observatories' Facebook page on May 14. The experts, not being able to completely comprehend the asteroid, again re-imaged it on 10 May and named it as 2010 WC9. "We, of course, collect astrometric data while this happens, but the movement of the asteroid will occur every five seconds".
