the heat from a star or planet
The comet's 'tail' always points away from the sun.
Generally, a comet has a single tail. However, one recent comet had "split" tails, and historical reports include other sightings of two-tailed comets.

Comets orbit stars
Comets have tails because when they approach the Sun, the heat causes their icy nuclei to sublimate, releasing gas and dust. This process creates a glowing coma around the nucleus and forms one or more tails that always point away from the Sun due to solar wind and radiation pressure. The tails can be made up of ionized gas (the ion tail) and dust particles (the dust tail), each forming under different conditions.
Mostly gas and ice

Bostons don't have a tail!
The word "comet" comes from the Greek word "kometes," meaning "long-haired." This term was used in ancient times to describe the appearance of a comet when its tail was visible in the sky. The name stuck and continues to be used for these celestial bodies today.
because of the sun's solar wind.
Unburnt fuel
The tail of a comet forms when the sun's heat causes the frozen gases and dust in the comet to vaporize and stream away from the nucleus. This creates two types of tails: ion tail (gas) and dust tail (solid particles). The direction of the tails is determined by the pressure of the solar wind.
