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.
Variations in the orbit of comets in the outer solar system can cause periodic comets to appear earlier or later than anticipated. We expect Halley's Comet to appear again in 2061. I don't believe that it would be accurate to narrow it down much further. Further, the telescopes of 2060 are likely to be orders of magnitude better than the current Hubble and Spitzer space telescopes. It is possible that astronomers 50 years from now will be able to detect the comet well in advance of it becoming a naked-eye object.
Halley's Comet is a well-known comet that orbits the Sun approximately every 76 years. It last appeared in 1986 and will next be visible from Earth in 2061.
The average distance of Chiron to the sun is 1224,557km away
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.
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).
45000 km (367 mi)
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.

Halley's comet orbits the Sun. It follows a highly elliptical path that takes it from the outer solar system, where it interacts with the gravitational forces of the giant planets, back towards the inner solar system, passing close to the Sun.
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!
Comet Halley is a famous periodic comet that orbits the Sun about every 76 years. It was last seen in 1986 and will next be visible from Earth in 2061. Its discovery and observation contribute to our understanding of comets and their trajectories.
Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
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.
