Many comets orbit the sun. How often we see them depends on their orbits. Halley's Comet, the most famous one, returns about every 75 years. It was last seen in 1986 and is expected again in 2061.

The most famous regularly returning comet is named Halley's comet. It nears the Sun every 74 years. Last seen in 1986.
Every 76 years or so. The last known sighting was in 1986, the next in 2061 or 2062.
Comets are the celestial bodies that appear in the sky at regular but long intervals and have a tail. This tail forms as a comet gets closer to the sun, causing ice and dust to vaporize and stream away from the comet, creating a bright extended tail.
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.
Beacause it completes its orbit in 76 years.
Yes.
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.
Solar winds blow the debris of the traveling comet to make it appear it has a tail.
