|content= | |content=Other presentations in this series have focused on the Earth's structure and others will consider its place in the solar system. Comets and meteors conveniently link them by considering the formation of planetary objects. Many people believe that a comet's tail is caused by friction as the comet moves through space. But this cannot be as the comet moves through a vacuum. In fact, the tail of the comet only appears when it is near the sun. The solar wind transfers energy to the comet and causes particles to be carried away in a stream of energy... The presentation is accompanied by a commentary from the teacher. | ||
|tagline=When a comet approaches the sun its tail is behind it. When it is moving away from the sun the tail is in front. Go figure. Or read more. | |||
