• Pluto IS a planet. I should know, I'm a Scorpio, the sign ruled by Pluto.
  • What is it? A fridge?

      It's too cold to be a fridge, but it'd make a good freezer if only it was easier to access.
  • Only if we are going to do the same for the 4 other dwarf planets. And there are several more that meet the dwarf planet requirements but aren't official. There could be hundreds more out there.
  • In the early 1800's, there were 23 planets. Then people started using the term "asteroid" to describe a planet that was too small to form a sphere. In 1930, the number of planets went from 8 to 9 with the discovery of Pluto. Then, in the late 1970's, it was discovered that Pluto was much smaller than originally thought, and just happened to be exceptionally reflective. In the mid-2000's with the Hubble telescope, astronomers discovered other planets that were the same size as Pluto, but just more difficult to see, so the conundrum once again arose as to whether those objects were planets or comets or asteroids or whatever, so astronomers agreed to remove Pluto from the list of planets and no longer have to worry about all of those other objects. The definition of "planet" was refined to be an object that has enough gravitational pull to clear its own orbit around the Sun, so Pluto was thus disqualified, since its orbit crosses Neptune's. It might be sad for Pluto enthusiasts, but the decision makes sense, and it's part of what makes science so cool. When something is found to be incorrect, scientists have no problem correcting themselves and moving on.
  • Yes. A dwarf Planet
  • No. An animated dog.
  • BostonJan64 has it right. What they did to it was not called for and simply not realistic.
  • Yes, it should still be considered a planet.
