Unless the asteroid actually STRIKES the Earth, then they have virtually no effect at all.

If the asteroid does strike the Earth, then it will cause damage like any other falling rock, although in this case the rock is falling at at least 25,000 miles per hour and may be tons or thousands of tons in size. An asteroid the size of a school bus exploded in the atmosphere over Chelyabinsk, Russia on February 15, 2013, causing millions of dollars in damage and causing over 1,000 injuries, mostly from flying glass.

If an asteroid the size of a ship were to hit the Earth (it has happened before!) it would cause continent-wide damage, and a really BIG asteroid could devastate the entire Earth.
