Abstract
The mean collision velocity between an asteroid and the Earth is found to be 20.8 km s-1. The standard deviation of the velocity data about this mean is 6.2 km s-1. The analysis of recently discovered Earth-cro ssing asteroids shows that the mean Earth-impact velocity decreases as the mean asteroid diameter decreases.
