Difficult to say as all the lengths will be different, depending on the size of the comet, the distance from the Sun, and amount of ejecta visible. While the solid nucleus of comets is generally less than 50 km across, the coma (The tail) may be larger than the Sun, and ion tails have been observed to extend 150 million km or more.
The length of the comet tail increases as it approaches the Sun because the heat causes volatile materials within the comet, like ice, to sublimate (turn directly from solid to gas). This process releases gas and dust particles, creating a long tail that points away from the Sun due to solar radiation and solar wind.
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.
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)
The longest comet tail on record belongs to the Great Comet of 1844, which had a tail that stretched for over 300 million kilometers. Comet tails can vary in length depending on factors such as the comet's size, composition, and proximity to the Sun.
The comet's tail is in front of the comet, not after
The coma, the nucleus, and the tail are the parts of a comet after the tail has formed.
The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.
yes. While one would presume that the tail would stretch out behind the comet, in reality the tail is caused by the solar wind blowing dust and gas away from the sun. Thus, no matter what orbit the comet is in or what direction it is travelling, the tail always points away from the sun.
Venus is a planet, not a comet, so it does not have a tail.

A comet
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.
