An asteroid of between 15 and 40 metres in diameter, unknown to the 4 of February, will pass very close to Earth this Friday, February 9, at a distance that only occurs once or twice a year.
2018 CB will reach its closest approach to 23.30 UTC, when it will only 64.000 miles of the surface of our planet, less than a fifth of the distance from the Earth to the Moon.
The asteroid, estimated to have between 15 and 40 metres in size, was discovered on the 4th of February by the Catalina Sky Survey (CSS), a telescope in Arizona, funded by NASA.
“Although 2018 CB is quite small, could be bigger than the asteroid that entered the atmosphere over Chelyabinsk, Russia, nearly exactly five years ago, in 2013,” said Paul Chodas, manager of the Centre of Studies of Near-Earth Objects at the Jet Propulsion Laboratory of NASA in Pasadena, California. “Asteroids of this size don’t normally get so close to our planet, perhaps only once or twice a year,” he says.
