The tail. The tail is composed of gas and dust released from the comet nucleus when it approaches the Sun. Comet tails can be incredibly long, some as long as 150 million kilometers.
As the comet recedes out into the Solar System away from the warmth of the Sun, it stops shedding dust and gas and the comet loses its tail.
During a comet's orbit, the coma and tails are the parts that come and go. The coma is the glowing, fuzzy cloud around the nucleus that develops as the comet gets closer to the Sun. The tails, consisting of ion and dust tails, form as a result of solar radiation and solar wind pushing the coma's particles away from the nucleus. Both the coma and tails diminish as the comet moves away from the Sun during its orbit.
It is highly imporbable that any comet follows a circular orbit. They are much more likely to follow long eliptical orbits in their eccentric wanderings through the inner and outer solar system. Surf the link to our friends at Wikipedia for some pics and more data.
Some meteor showers are caused by Earth passing through the remnants of an old comet or parts of the trail of debris left by comets. The Leonid meteor shower is caused by Earth passing through the trail of comet Temple-Tuttle.
That all depends on the comet Halley's takes about 76 years where as Hale Bopp takes about 2300 years. Its the same principle with the planets the closer the orbit the faster it goes. Some Comets like Hale Bopp come from the Oort cloud about a light year away that is why it takes so long, where as Halley's goes out round Pluto and back again.
They are from extreme outer parts of the solar system (known as "Kuiper belt") and from a huge cloud of comets lying far beyond the orbit of Pluto, completely surrounding the Sun (known as "Oort cloud").
A comet's 3 main parts are nucleus, coma and tail. The nucleus is the heart of a comet. A coma is the gas and dust that forms a cloud around the nucleus. The tail is a blazing streamer from the coma, it is million of miles long
Pluto is a dwarf planet. It could be an asteroid, or it could be a moon that escaped the orbit of Neptune. It could Not be a comet. Comets are chunks of frozen ice that travel in orbit around the sun, and as they near the sun, parts of the comet melt and leave a trail of melted water in their wake. Pluto never gets near the sun to melt. Pluto never gets nearer the sun than the orbit of Neptune.
The trajectories of all observed comets to date have been elliptical, indicating that they orbit the sun. A comet coming in from outside the solar system would follow a hyperbolic trajectory.

70%-80% of the comet is dry ice. The other 20%-30% is metal and rock. A comet has three main parts they include a head, a coma, and a tail. and it orbits the sun with an oliptical orbit, comets come from the oort cloud outside of our solar system or Kuiper belt which is a bit past neptune. Meteors, are rocks roaming space on a predicted path, made of iron, and other metals and rocks

Although sometimes not visible from parts of the planet, comets can be seen from very large geographical areas on Earth, not only from individual locations.

They all orbit around the sun.
The three main parts of a comet are the nucleus, coma, and tail. The nucleus is the head of the comet, the coma is the middle, and the tail is the end of the comet.
They are from extreme outer parts of the solar system (known as "Kuiper belt") and from a huge cloud of comets lying far beyond the orbit of Pluto, completely surrounding the Sun (known as "Oort cloud").
The coma, the nucleus, and the tail are the parts of a comet after the tail has formed.
