A bigger rock, say one the dimensions of a 20-story constructing, would crush something inside 5 miles of the purpose of influence.

Fortunately, in response to Richard Binzel, a professor of planetary sciences at MIT, there are not any large rocks in house that we all know of that would develop giant sufficient to utterly wipe out life on Earth. At least not but.

The subsequent time an asteroid will move very near Earth it is going to be on October 26, 2028. It is projected to be about two and a half instances the space from the Moon to Earth at its closest level.
