Is Pluto a comet?
It is not fact, but Pluto cannot possibly be a planet; it is too small. Even if it does have Charon (moon), It is not big enough to be a planet (my opinion).
Also, its orbit is elliptical, and comes closer to the Sun, intercepting and passing through Neptune's orbit. As many people know, all of the solar systems comets go far away from the sun, and then come plowing back and going very close to the surface of the sun, before setting off again as far as it can again.
The only difference between other comets and Pluto is that Pluto doesn't develop a "tail"
Pluto travels at different speeds on its course to orbit the Sun, thus proving my point that Pluto is in fact a comet, and not a planet.
