Small Asteroid in Friday's Earth Fly-by Just 39000 Miles Away

Small Asteroid in Friday's Earth Fly-by Just 39000 Miles Away”

According to NASA, it will make its closest approach to Earth at 10:30 p.m. GMT (5:30 p.m. EST) today.

'The just discovered 2018 CC and 2018 CB near-Earth asteroids will both have a very close, but safe encounter with the Earth soon, ' a spokeswoman for the Virtual Telescope Project wrote earlier this week. The huge space rock was discovered along with another smaller asteroid by the NASA-funded Catalina Sky Survey (CSS) near Tucson, Arizona, Sunday.

"Asteroids of this size do not often approach this close to our planet, maybe only once or twice a year", said Paul Chodas, manager of the Center for Near-Earth Object Studies at JPL.

"Asteroid 2018 CB" will be about 39,000 miles away when it zooms past. The asteroid is approximately 1,000 feet or more than 300 meters across.

The shock wave following a 20-metre wide asteroid hitting the atmosphere over Chelyabinsk injured nearly 1,000 people on February 15 2013.

It will be the second time this week that an asteroid flies by us because on Tuesday, an asteroid passed the Earth within 114,000 miles, which is about hallway to the moon in distance. It was estimated at 50 to 100 feet in size, JPL said.

Scientist had been tracking Asteroid 202 AJ129 for about a year and knowing all along that this medium sized space rock posed no threat to Earth.

The agency has found about 16,000 asteroids and comets near Earth, and there are another few million estimated to be orbiting the sun between Mars and Jupiter, where a lot of them reside.
