What is the difference between a coma and a tail of a comet?

A comet is a small icy celestial body that orbits around the sun. It is made up of ice, rock, dust, and frozen gases that are all held together by gravity. When a comet is heated by the sun's radiation, its ices begin to vaporize, creating a cloud of gas and dust called a coma. The coma is the fuzzy atmosphere that surrounds the comet's nucleus and can extend over millions of kilometers.

The coma is different from the tail of a comet. The tail is a long, thin stream of gas and dust that is blown away from the coma by the solar wind. The solar wind is a stream of charged particles that is constantly blowing from the sun, and it can blow the tail of a comet millions of kilometers away from the coma. The tail always points away from the sun, and it can be visible for several weeks or months as the comet moves through space.
