We believe comets have a composition like a dirty snowball. They contain alot of ice and dust. The ice does trun into a gas when the comet approaches near to the sun and this causes the comet's tail to form.
The "nucleus" of the comet is the solid part. The coma and the tail are mostly gas and dust, which glow by reflected sunlight. Without the gas and dust, most comets would be invisible asteroids.
Meteors would be solids, but much of their mass vaporizes during atmospheric entry.
An asteroid is solid. it is composed of rock and/or metal.
The center of a comet is called its nucleus.
nucleus. it is the only solid part and although you cant always see it it is always there.
The nucleus is very small, often only a few kilometers across. Scientists describe the nucleus as a "dirty snowball." It is made of dust and ice-frozen water and frozen gases. Over time, the nucleus becomes more and more black and solid. As water and gases evaporate from the surface, dark, heavy tar-like matter gets left behind.
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.'

The solid object at the head of a comet is called the comet nucleus.
No it is not its the nucleus
