At it's furthest point from the sun Halley's comet is about 4.5 light hours away (1/2000 of a light year) At the moment it is about 3.5 light hours away. At it's furthest point it is just inside the orbit of Pluto.
At its last perihelion, in 1986, Halley's Comet passed 0.586 AU = about 54.5 million miles
from the sun. Its orbit is subject to perturbation by the planets it passes, so the minimum
distance is not necessarily constant from one orbit to the next.
Hally's Comet orbits the Sun once every 76 years. It has a long, elliptical orbit with an average distance of 1,720,500,000 miles.
35.1 AU Out a little past the orbit of Neptune.
It depends
The average distance of Chiron to the sun is 1224,557km away
The moon is approximately 75 au's from the Earth The above answer is absurd. One Astronomical Unit (AU) is the mean (average) distance from the Earth to the Sun. If that answer was correct, the Moon would have to be 75 times further from Earth than the Sun! The average distance from the center of the Earth to the center of the Moon is 0.00256957366 AU or 384,403 kilometres (238,857 mi).
One AU is the distance between the Earth and the Sun.
Halley's comet loses a bit of mass every time it makes a trip around the sun. Eventually, it will run out of volatiles (gasses) and become an almost invisible asteroid. There is the possibility that it might crash into something. While I don't believe its course intercepts any planets currently, the outgassing could change the course enough to cause Halley to crash into a planet. In 1994, that fate befell Comet Shoemaker-Levy which fell dramatically into Jupiter.
No. Earth to the Sun is: Average Distance is 15o million km Earth to the Moon is: Average Distance is 384403 kilometers
45000 km (367 mi)
Halley's Comet orbits around the sun.
Halley's Comet orbits the Sun, in an elliptical path. It doesn't orbit anything else.
Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.
Halley's Comet is currently a little beyond the orbit of Neptune.

No. Comet brightness depends on the actual brightness, but also on the distance from the Sun. In 1986, Halley's Comet was not very bright, because it was far from Earth. The previous appearance in 1910 was distinctly brighter, but still wasn't even the brightest comet of the year; the "Great Daylight Comet of 1910" was visible during the day!
Halley's Comet orbits the sun, not the earth, roughly every 76 years.
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.
As of May 2010 Halley's comet is 32 Astromical units from the Sun (4,800 million km's) For location, click on the link below.
It's not in Earths orbit. Halley's orbit [See Link] is highly elliptical, and focused on the Sun. Its perihelion, its closest distance to the Sun, is just 0.6 AU (between the orbits of Mercury and Venus), while its aphelion, or farthest distance from the Sun, is 35 AU, or roughly the distance of Pluto
