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.

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.

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.
No. The tail of the comet points away from the sun.
The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.
