Two small asteroids safely pass Earth this week


After all, it's not every day that a space rock flies this close to the Earth, and scientists at the Jet Propulsion Laboratory in La Cañada Flintridge say there is no chance it will impact the planet.

According to NASA, it will make its closest approach to Earth at 10:30 p.m. GMT (5:30 p.m. EST) today.

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

"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 Paul Chodas, manager of the Center for Near-Earth Object Studies at NASA's Jet Propulsion Laboratory in Pasadena, California.

The path of asteroid 2018 CB, which will come close to Earth on February 10.


The Catalina Sky Survey is part of an initiative to look for potentially hazardous asteroids (PHAs) and there are several networks around the world with the same goal. The asteroid was estimated to be 55-65 feet in diameter.

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.

The second asteroid in a week will be passing close to earth on this Friday afternoon. It was estimated at 50 to 100 feet in size, JPL said. Although this distance was greater than the close distance of 2018 CB, NASA feels that these two asteroids came unusually near to our Earth during their close flyby.

The agency has found about 16,000 asteroids and comets near Earth, and there are another few million estimated to be orbiting the sun between Mars and Jupiter, where majority reside.

The first was called 2018 CC and zoomed past at 8:10 p.m on Tuesday.
