They vary in speed, depending on what reference point you use. Some of the Perseid meteors this year were measured at about 160,000 miles per hour!
Most are moving more slowly, but the minimum speed is about 25,000 miles per hour, which is the speed that an object would have if it fell from space without any initial velocity.
