Are asteroids dangerous?

Answer :

A An asteroid can be thrown off its orbit by the gravity of larger planets, or if it comes too close to another asteroid. Once it is off its orbit, the stray asteroid often strikes the surface of other planets and moons. This causes widespread destruction and creates huge craters. In fact, some scientists think that an asteroid struck Earth about 65 million years ago, causing the extinction of the dinosaurs.
