Mystery stuff

Long ago, the sight of a comet frightened people. With its bright head and long, wispy tails, comets did not look like anything else in the sky. And, unlike the sun, stars, and moon, comets did not seem to appear on any schedule. Comets were a deep mystery. Comet's tail always points away from Sun.

We now know that comets are part of our solar system. Like the planets, they orbit the sun. Some comets, called short-period comets, take up to 200 years to make one orbit. But some comets have orbits so big and elliptical (shaped like a squashed circle) it may take millions of years to make one trip around the sun!

Comets are the icy leftovers from when our solar system formed. We can learn much about how the solar system began by studying comets.
