I've always doubted that Pluto was a planet..
QUOTE The scientists agreed that for a celestial body to qualify as a planet: * it must be in orbit around the Sun * it must be large enough that it takes on a nearly round shape * it has cleared its orbit of other objects Pluto was automatically disqualified because its highly elliptical orbit overlaps with that of Neptune. It will now join a new category of dwarf planets. That means that Pluto can't be a planet because it's orbit crosses Neptune's. And since a planet has to have "cleared its orbit of other objects", Pluto can't be a planet. By the way, this is a very interesting article regarding Pluto's planethood. |
