Halley's comet has a period of 76 years so its average distance, i.e. the semimajor axis of the orbit, in astronomical units, is 762/3 by Kepler's third law.
That is 17.9 astronomical units or 2700 million kilometres.
The distance varies from 0.6 to about 35 astronomical units. The orbit is retrograde, meaning that this comet goes round the wrong way. The orbit is inclined by 19 degrees to the ecliptic and the comet spends most of its time in the Southern Hemisphere.
Edmund Halley was the second Astronomer Royal, who took over from the Rev. John Flamsteed. Flamsteed did not like Halley and said, "Mr Halley smokes, swears and drinks brandy like a sea captain". Mrs Flamsteed was instructed to sell all the instruments at Greenwich Observatory in Flamsteed's will, so Halley had to start over again.

A comet has the most potential energy at its farthest point from the sun (aphelion) in its elliptical orbit. At this point, the comet's gravitational potential energy is maximized due to the distance from the sun being at its greatest.

No. The tail of the comet points away from the sun.

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.

Hayley's comet is not always the same distance from the sun. This is because it has an elliptical orbit. When the comet is closest to the sun the ice begins to burn up forming the tail.
A comet has the most potential energy at its farthest point from the sun (aphelion) in its elliptical orbit. At this point, the comet's gravitational potential energy is maximized due to the distance from the sun being at its greatest.

The average distance of Chiron to the sun is 1224,557km away
The same as the Earth
The moon's average distance from the sun is exactly the same as the earth's average distance from the sun.
A comet has the greatest potential energy at its farthest point from the Sun, known as aphelion. At this location, the gravitational pull of the Sun is weaker, and the comet is at its maximum distance from the Sun. As the comet moves closer to the Sun in its elliptical orbit, its potential energy decreases while its kinetic energy increases due to the gravitational attraction.
