Description:
During the last few years it has become widely recognized that from time to time the Earth is hit by large objects from space. These are now known to be responsible for what are called 'extinction events' when most of the existing life forms went extinct suddenly. The Earth is traveling through space at quite high speed around the Sun and the Sun is orbiting the centre of the galaxy.
