Some are light years long and some just few thouand miles long
The tail of a comet is over a million miles long.
The "Comet" is a variety of Goldfish that has a long, single tail.
Comets are the celestial bodies that appear in the sky at regular but long intervals and have a tail. This tail forms as a comet gets closer to the sun, causing ice and dust to vaporize and stream away from the comet, creating a bright extended tail.
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 comet's tail can vary in length, but it can extend from tens of thousands to millions of kilometers. The tail is mainly composed of dust and gas particles that are released as the comet approaches the Sun and interaction with solar wind pushes the material away from the comet's nucleus.
A comet's tail is long and glowing because it contains gases, dust, and debris that are illuminated by the Sun as the comet travels through space. The tail always points away from the Sun due to the solar wind pushing the materials in the tail.

The tail of a comet is made up of a combination of frozen rock, and ice particles coming off the comet and is lit up by the sun. If you were to be in this tail, you would face: subzero temperatures and constant pummeling by SOLID ice and rock.
Most comet tails are millions of miles long, for example the Halley's comet, with a tail stretching 50 million kilometers. As well as the Great Comet of 1843, the tail reaching 2 AU in length. (One AU is about 150 000 000km)
