A comet is a ball of mostly ice that moves around in outer space. It is similar to an asteroid. In Earth's solar system, the orbits of comets go farther than Pluto, a dwarf planet that used to be the farthest planet from the Sun. Most are very far away from the Sun, but some come near enough to Earth for us to see at night. They have long "tails", because the Sun melts the ice. Sometimes people call them "dirty snowballs" or "shooting stars".
The hard centre of the comet is the "nucleus". It is one of the blackest things in the solar system. When light shone on Comet Halley's nucleus, only 4% of the light shone back to us.
"Periodic" comets visit again and again. "Non-periodic" or "single-apparition" comets visit only once.
People have seen some comets when they broke into pieces: Comet Biela was one example. Another comet was seen when it hit a planet: Comet Shoemaker-Levy 9 hit Jupiter in 1994. Some comets orbit (go around) together in groups. Astronomers think these comets are broken pieces that used to be one object.
History of comets.
In old times, people used to be scared of comets. They didn't know what they were, or where they came from. Some thought that they were fireballs sent from demons or gods to destroy the earth. They said that each time a comet appeared, it would bring bad luck with it. Whenever a comet appeared, a king would die. One of these examples is shown in the Bayeux Tapestry, when Halley's Comet returned. Comets were also known to end wars and though -
