Heads Up, Earthlings: Asteroid Close Encounter Ahead

Adjust Comment Print

While asteroid 2018 CC safely skimmed past Earth on February 6 at 12:10 p.m. PST (3:10 p.m. EST), the other asteroid 2018 CB is all set for a close flyby of Earth on February 9, Friday.

An asteroid discovered last week is due to fly past the earth at 10.30pm this evening.

The asteroid is estimated at about 50 feet to 130 feet in size, possibly a little larger than the asteroid that exploded over Russian Federation five years ago this month.

The space agency only caught sight of the pair of asteroids on Sunday - just days before they were due for a close encounter with our planet.

Paul Chodas of NASA's Center for Near-Earth Object Studies, told The Guardian that asteroids of this size don't often come close to our planet.

2018 CB will pass within 39,000 miles (63,000 km) of earth, which is less than one-fifth the distance between the earth and the moon.

The asteroid was found by NASA-funded Catalina Sky Survey (CSS) near Tucson, Arizona, that records potentially hazardous asteroids.

Designated 2018 CB, the asteroid is an estimated 15 metres to 40 metres in size, possibly bigger than the one that exploded over Russian Federation five years ago this month.

During the 2013 Chelyabinsk event, 1500 people were injured and 7300 buildings damaged by the intense overpressure generated by the shockwave at Earth's surface. Scientists calculated its closest approach was a distance of 114,000 miles from Earth.

The second asteroid in a week will be passing close to earth on this Friday afternoon. The asteroid was between 50 and 100 feet in size.

The asteroid is now known as 2018 CB, and its closest approach comes on the heels of another asteroid flyby, which occurred Tuesday at 12:10 p.m.
