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)

Celestial comets is a more formal name for comets. Comets are objects in space orbiting the Sun with long orbits. They are thought to be made of frozen water. As they near the Sun they produce a long glowing tail trailing behind.
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 star with a long tail is typically referred to as a comet. Comets are icy bodies that release gas and dust as they approach the Sun, forming a glowing coma and a tail that points away from the Sun due to solar wind and radiation pressure. The tail can appear quite elongated and is one of the most distinctive features of comets.
Comets are made of mainly 3 parts -dust tail, ion tail and coma

The mass of material with a long tail that travels around the sun is called a comet. Comets are composed of ice, dust, and small rocky particles. The tail of a comet is formed when it gets closer to the sun, and the heat causes the ice to vaporize and create a glowing tail. The mass of a comet can range from a few million kilograms to billions of kilograms.
