Question

What is the speed of a asterioid?

Answer 1

the sped of an asteroid is 25 kilometers per second

Answer 2

An asteroid moves with an average speed of 25 kilometers per second, so it should be no closer to the Earth than 464,000 kilometers when a bomb targeting it goes off. Detractors argue that using such a method would be extremely unwise and fraught with grave implications for the Earth.
