A comet is a remnant from the formation of stars and planets billions of years ago.
It is made of ice and rocks.
As the comet is hurled toward the sun by gravitational forces, its ice is vaporized. That forms the tail of the comet.
The tail always points AWAY from the sun, not necessarily in the opposite direction of its movement through the solar system.
