The space rock, called 2015 FF, has an expected width of somewhere in the range of 13 and 28 meters - around the equivalent of a grown-up blue whale.
Going towards the Earth at 20,512 miles each hour, it will come multiple times the distance between our planet and the Moon , 4.3 million kilometers into space.
Nasa characterizes any item that comes extremely close to Earth as a "close Earth object", while anything that goes inside 7.5 million kilometers is classified as "possibly dangerous."
A surprising effect from another space rock could without much of a stretch send the stone rushing towards Earth.
The planet has some early-cautioning frameworks to get ready people for an impact. In March, the European Space Agency's planetary protection local area detected a space rock hours
Nasa has likewise been planning shuttle that could stop a possible perilous impact. Recently it sent off Dart or Double Asteroid Redirection Test
The mission will just knock the space rock off its circle by somewhat, even at a speed of 15,000 miles each hour
However, that is everything necessary to put it off base, in the event that researchers can detect possibly risky space rocks adequately early
On the off chance that they can't, in any case, the outcomes could demolish. Seven days in length practice drove by Nasa presumed that disaster would be undeniable on the off chance that a huge space rock was going to Earth
