Known as 2018 CC, the object made its closest approach to Earth on 6 February at a distance of about 184,000km (114,000 miles).
The asteroid was given the catchy name 2018 CB when it was discovered at the Catalina Sky Survey, a series of Nasa-funded telescopes in Tuscon, Arizon, last Sunday.

A recently discovered asteroid was due to zip within 39,000 thousand miles (64,000 km) of Earth on Friday, marking the second space rock to pass within the orbit of the moon this week, according to NASA scientists.
The moon is an average of 240,000 miles from Earth.
It is one of pair of asteroids which will pass by our planet this week. Asteroid 2002 AJ129 approached the planet at a distance of 2.6 million miles away, which is 10 times the distance to the moon.More news: 49ers Make Jimmy Garoppolo Highest-Paid Player In NFL

"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", Paul Chodas, manager of the Center for Near Earth Object Studies at NASA's Jet Propulsion Laboratory, said in a statement.
It's between 50 and 130 feet wide, similar in size the one which exploded over Chelyabinsk five years ago.
NASA has revealed that an asteroid dubbed 2018 CB will flyby Earth closely on Friday, February 9.
Neither asteroid poses a threat to Earth.
In the meantime, astronomers are looking out for asteroids in the far cosmic reaches.
According to NASA's Center for Near Earth Object Studies 13 other close approaches are set to take place this month, followed by five in March.
