Why do astronomers search for near earth asteroids?
Near-Earth asteroids have some potential to collide with Earth. The effects of an impact, even from a relatively small asteroid, could be devastating. So, scientists are working to find objects that might collide with Earth. If one is shown to be a substantial danger, then strategies for deflecting it to miss earth may be discussed.
Are asteroids larger then earth?
