The second asteroid, called 2018 CB, will pass near Earth around 5:30 p.m. EST Friday at distance of about 39,000 miles, less than one-fifth of the distance between Earth and the moon, according to NASA.
"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 of NASA's Jet Propulsion Laboratory in Pasadena, California.
A large space rock will is headed towards Earth and will come terrifyingly close to our planet this evening.
Paul Chodas of NASA's Center for Near-Earth Object Studies, told The Guardian that asteroids of this size don't often come close to our planet.
The first was called 2018 CC and zoomed past at 8:10 p.m on Tuesday.
This recently discovered asteroid it estimated by NASA to be anywhere from 50 to 120 feet across.
The "Super Bowl asteroid" garnered a lot of attention when it passed Earth right around the same time the big game kicked off Sunday.
"2018 CB will be traveling at around 26,000 miles per hour (58,000 km/h)".
Besides its close approach to Earth on Friday, 2018 CB will also fly past the Moon one day later at around 12:56 UTC at a distance of 0.79 LD, or 188,000 miles (303,000 kilometers).
The space agency has assured people it does not pose an actual threat of colliding with our planet.
Currently Nasa would not be able to deflect an asteroid if it were heading for Earth but it could mitigate the impact and take measures that would protect lives and property.
On Feb. 15, 2013, an asteroid roughly 17 metres in size lit up the sky over Chelyabinsk breaking up, with a large piece landing in a lake. Nowakowski's generous offer was gratefully received with the two organizations now working to better relay important developments as they pertain to space exploration.
