The tail of a comet is over a million miles long.
Sure. As a comet approaches the sun, the comet sheds some of its material, which trails behind it for millions of kilometers. It is this tail that is the most visible part of a comet. In fact, the word comet means "hairy star," referring to the long, streaming tail. In 1910, the earth actually passed through the tail of Halley's Comet.
a tail
Halley's comet, the actual solid nucleus part, is around 8km wide by 15km long. It's gas and dust tails can be spread out over millions of km though. The diameter of the Earth is around 12,700 km, so by contrast, the diameter of the nucleus of Halley's comet is around 0.1% the diameter of Earth.
The nucleus is the solid part of a comet.
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.'
