Asteroid to closely pass by earth on Friday

Paul Chodas, manager of NASA's Center for Near-Earth Object Studies, said that such asteroids "do not often approach this close to our planet - maybe only once or twice a year".

Both asteroids were discovered February 4 by the Catalina Sky Survey, a NASA-funded group based in Tucson, Ariz.

The rocky visitor was first spotted Sunday by the Catalina Sky Survey - a series of three telescopes located in the Santa Catalina Mountains north of Tucson.

The asteroid is estimated to be between 15 and 40 metres in size.

Apart from these two asteroids, another spooky asteroid named 2015 TB145, which is known as the Halloween asteroid because of its appearance, is going to fly by our planet this year.

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.

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.

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. Scientists estimated the asteroid was 50-100 feet in diameter.

AN asteroid heading for earth this evening has been described by NASA as "potentially hazardous".

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.
