Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.

Pluto has a moon nearly half its size.?Pluto's diameter is about 2300 km, while its moon Charon has an estimated diameter of 1200 km. Of course, remembering that volume is related to the cube of linear dimensions, that means Pluto's volume is actually about eight times that of Charon.
