 * by Mr Marley**

An asteroid or comet strike would be a rare event, but scientists believe it has happened in the past. A long time ago, when Earth was a young planet, the Solar System was filled with smaller bodies which made impact with the planets. Many believe that an asteroid or comet hit the Earth in the time of the dinosaurs, causing their extinction.

In his TV series //Cosmos,// the astronomer Carl Sagan talks of the Tunguska Event, which scientists believe was caused by a meteor or comet. On June 30, 1908, there was a huge explosion near the Tunguska River in Russia. Little property damage or injury to people was recorded because the river is in a remote part of Siberia. Scientists studying the location and the after effects think a small object might have struck the Earth. You can read more about it in the Wikipedia article:-

I am fascinated by asteroids. In 2004 I wrote a reflective piece called //The Asteroid Project//. You can download it below.
