What is interesting to note is that the asteroid was discovered by astronomers at the NASA-funded Catalina Sky Survey (CSS) in Arizona very recently - on February 4.

Asteroid 2018 CB will pass by at just less than one-fifth the distance between the Earth and the Moon.

An asteroid is headed our way - the second this week - but there's no need to worry.

NASA said 2018 CB will safely pass the Earth at a distance of 39,000 miles, pretty close by space standards.

Unlike the Chelyabinsk rock, though, this asteroid will miss our planet, passing by Earth on Friday evening British time.

It's between 50 and 130 feet wide, similar in size the one which exploded over Chelyabinsk five years ago.

The first of this week's close-approaching asteroids-discovered by CSS on February 4-is designated asteroid 2018 CC.

"Although 2018 CB is quite small, it might well be larger than the asteroid that entered the atmosphere over Chelyabinsk, Russia, nearly exactly five years ago, in 2013", said NASA's Paul Chodas.

On Tuesday, 2018 CC was about 114,000 miles away when it flew by Earth. Last year, more than 2,000 previously unknown near-Earth asteroids were discovered, according to Chodas. In the meantime, astronomers are on the lookout for asteroids lurking in the cosmic shadows.

Another small asteroid passed within lunar distance this week.

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