A tail
Comet tails always stream away from the sun due to the solar wind, which is a stream of charged particles emitted by the sun. The solar wind pushes against the gas and dust particles in the comet's coma (a cloud of gas and dust surrounding the nucleus) and causes them to form a tail that points away from the sun.
A comet's tail is only seen when the comet is relatively close to the Sun. The heat of the Sun evaporates particles from the comet and illuminates them.Far from the Sun there is neither evaporation nor illumination.If a comet tail is not visible, then probably it doesn't have a tail. The comet has a tail when it comes near the Sun, and gets heated up. It is interesting to note that the comet's tail will always point away from the Sun (it gets blown out by the solar wind), this may be "behind" or "in front of" the direction of movement of the comet.Usually, the center of a comet is composed of ices and meteoric materials. These ices are sublimated (transformation of solid into gas) under the action of sunlight when the comet goes to the sun. The dust and ice (that is transformed into gas) are expelled from the center of the comet. Ultraviolet radiation from the sun breaks the molecules of gas and dust. These broken molecules becomes bright because of exposition to ultraviolet. That's why we can see a comet's tail.
A comet usually has two tails, though only one - the vapor trail - is commonly seen from earth (the other is a gas trail). It is made of vapor blown off from the comet by the solar wind - it is mostly water vapor, but contains many other molecular substances, too - ammonia, cyanide, methane, etc.
The Comet's Tail forms when sunlight causes the Comet's ice to change to a gas. The gas or ion , tail of a comet streams from the comet's head, carrying with it dust particles. The solar wind electrically charged particles, expand away from the sun pushes the gas away from the comet's head. Regardless of where its going the tail points away from the sun.
It is called a comet.

Comets have a stream of gas and dust coming off them.
The nebulous halo around the nucleus of the comet is called the "Coma" ...The stream of dust and gas that extends away from the comet is called the"Tail".

A comet
A comet's "tail" points away from the Sun. Moving away from the Sun, that means that the comet is moving "tail-first" through space. This is because the comet's tail is actually just wisps of gas and dust melting out of the "nucleus" or head of the comet. The light of the Sun actually has a pressure, and this solar pressure blows the dusty gas away from the comet itself. It is this dusty gas reflecting the Sun's light that we see.
