The nucleus is the bulk of the comet, this is present all the time until it eventually breaks up after many orbits. close to the sun, it gives of two tails as the sun heats the comets surface. Far from the sun it would just look like a rock that also contains a high proportion of ice.

Sozin's Comet part 4: Avatar Aang P.S. i don't know if you know this, but a new series of Avatar is coming out! It's about the avatar after Aang, a waterbender names Korra. It is 80 years later, so the world has advanced technologically. And, you see many of the characters from Avatar: The Last Airbender (who are considerably older now) AND there is a place called the republic where all nations can live. Another thing that is cool about the upcoming series is that either Aang and Katara's son is her airbending teacher! You can look forward to this series coming either Summer or Fall 2011.
Basically the evaporated gas of whatever the comet nucleus is made of. Often methane, ammonia, carbon mon- and di-oxide. A very good article is in the link below. However, due to relative motion and a few other forces, the tail is not all that straight.
Ridley Scott is British, so he would not be part of American politics. Do you mean conservative?
The Libyan Desert, part of the much larger Sahara, covers most of Egypt.
Near the sun: A cometary nucleus has a "corona" (a vapor outgassing of it's nucleus, up to a million times wider than the comet itself - this is what we see as the "head" of the comet), and one or several "tails". The "tail" we usually see is the vapor trail, but sometimes a secondary gas trail is also visible. Far from the sun, it is just the nucleus. Typically 3 to 10 kilometers wide, oddly shaped, like a potato or a peanut and, somewhat surprisingly , very dark in color, like soot.
The nucleus is the solid part of a comet.
A comet may, or may not, have a tail. It will have a tail if it gets sufficiently close to the Sun; in this case, it will start to heat up, part of its material will evaporate, and the solar wind will push this gas out into space.A comet may, or may not, have a tail.

Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
tail
The head of the comet
Yes,it is.
We onnly see a comet for a very short part of their orbit because they travel in very elongated elliptical orbits with the Sun near one end. So they are only close to the Sun for us to see their reflected light for a short time.
The orbits of comets are elongated ovals that take the comet around the sun and then far out beyond Pluto. We can see them only in that part of their orbit which brings them close to the Earth

Me
Yes. In fact, with the extremely rare exception of a "rogue" comet, all comets are a part of our solar system.
