Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.
The sun makes a comet appear bright. A comet is usually made up of ice and rock. The ice reflects the light of the sun very well.
Pluto makes a complete orbit around the sun every 248.09 years.
Comet Halley is currently still sailing away from the Sun and most of the planets in our solar system as it makes its way to its aphelion (farthest point from the Sun) in 2024, out around the orbit of Pluto. It was last closest to the Sun in 1986, and will return to perihelion (closest to the Sun) in 2061.
