Halley's Comet orbits the sun every 75.3 years. For most of this time it is far out from the sun, up to 35 Astronomical Units (or AU, where 1 AU = sun to earth distance). At this distance, its speed is a lot slower, and it has no tail due to the low temperatures at this distance.
It last appeared in our skies in 1986, it will not be around again until the middle of 2061.
The Sun does not revolve around itself; it rotates on its axis. It takes about 25 Earth days for the Sun to complete one rotation.

It takes Saturn 29.45 years (or 10759 days) to orbit, or revolve around, the Sun once. It takes about 29.5 Earth years for the planet Saturn to revolve once around the sun. 10,579 earth days
That depends on what you call 'long' or 'short'. Halley's period is in the neighborhood of 75 years, give or take a few years. Since that's short enough for two perihelions to occur within a single human lifetime, I guess it ought to be considered a short period.
Yes, all planets in our solar system revolve around the sun

Nothing much, recently. Halley's Comet is out beyond the orbit of Neptune. moving slowly through space near the peak of its path through the solar system. Because it is so far from the Sun, it is frozen solid, with not gaseous coma reflecting the sunlight. And because comet nuclei are fairly small, it is invisible in all except the largest telescopes.

Betelgeuse doesn't revolve around the sun. It is a star, even larger than the sun, and much too far away for the sun to have much effect on it.

Uranus needs about 84 Earth years, or about 30,685 Earth days, to revolve around the Sun. This is also known as its period of revolution.
