But it will be about 3.2 million kilometers away from our planet, 13 times farther from the moon, NASA says, so there’s really no reason to worry.
And such phenomena are quite normal. Last August, an asteroid estimated to be about the same size as the 2002 NN4 that passed by Earth, and experts at the time called it moderate in size.
However, the probability that the asteroid will actually hit the Earth is quite small – it occurs once in two or three centuries, Johnson said at the time.
Since it is a million miles away, this should not be the case with the 2002 NN4. So you can spend Saturday night relaxing, knowing that the asteroid isn’t actually coming to us to explode. Today, at least.
The next time NN4 will be anywhere near us will be in June 2029.
