Travelers In The Night

Every month we discover small asteroids which come closer than the Moon. There are probably 20 million asteroids in this size range which come near the Earth. A few of these may eventually impact our planet. Those that do are likely to explode high in the atmosphere producing a supersonic boom. We are not more likely to be hit by a small asteroid than we have in the past. However, we are becoming more likely to be able to provide a tornado like warning for people in the affected area to stay away from doors and windows.
