It is two planets together as it shares its center of gravity with Charon in the space between them.
Pluto is not classified as a planet because of several reasons. one reason is that its moon is about half the size of the planet, and no planets moon is even close to being half the planets size (it goes into gravitational laws and gets pretty complicated so lets leave it at that). another reason is that plutos planet is not elliptical. All the planets orbits are elliptical, for the most part. Elliptical is not spherical, but not necessarily oval either. its like a slightly stretched sphere, but not stretched enough to be oval. Plutos orbit crosses over neptunes. one last reason is that there have been objects found past Pluto that are very similar to Pluto, in size and appearance, and these objects are not planets there are more like comets or asteroids, so it is possible that Pluto is one of these objects in close range to the sun.
A lot of debate still rages over this decision. The most common argument is that Neptune can't be a planet either because it hasn't cleared its neighborhood of Pluto. The idea of dwarf planets isn't a bad one, but we need a far more static criteria to sort out what is an asteroid, a dwarf planet, and a planet.
Neptune is most definitely a planet.
Its debatable, some people don't like it being classified as a dwarf planet and would rather it remain as one of the main planets. It was known as the ninth planet for a long time, from its discovery in 1930 to its reclassification in 2006.
With newer objects being discovered of a similar size (or even larger in the case or Eris) we either had to add to the list of planets, call a stop and just leave the nine planets as they were or reclassify what a planet actually is.
Pluto was re-classified as a dwarf planet on August 24th 2006 by the International Astronomical Union (IAU). A new definition for a planet was established, Pluto did not fit the new criteria, so was deemed a dwarf planet - known to be spherical in shape and orbit the sun directly, but not dominating its orbit like all 8 remaining planets.
No, it is a dwarf planet.
Pluto is no longer considered a planet, it is now classified as a "Dwarf Planet". As a planet or a dwarf planet, Pluto was the smallest in our solar system. Mercury is now the smallest recognised planet. Pluto's equatorial diameter is 2,274 km. Mercury's equatorial diameter is 4,880 km.
Mercury, because it's the smallest if you don't consider Pluto to be a planet.
Charon, Nix and Hydra are the 3 moons of Pluto. Pluto is no longer considered to be a planet, but is classified as a dwarf planet.
Pluto has three moons but is no longer classified as a planet.
All of the eight planets are all lesser planets but Pluto isn't a planet so it isn't a lesser planet
Pluto is no longer a planet but is classified as a dwarf planet, So Pluto is classified as a dwarf planet. Neither terrestrial or gas planet.
No. Pluto is a dwarf planet that was once classified as a planet.
As of 2006, Pluto has been classified as a dwarf planet.
No, Pluto is no longer classified as a plant. It is now known as a dwarf planet.
Pluto.
Pluto has been re-classified as a Dwarf Planet.
Pluto, it was re-classified as a dwarf planet.
No. It is too small to be classified as a planet.
Pluto is classified as a big ball of gas now, so Pluto is not considered as a planet anymore.
No, Mars is the fourth planet from the Sun. Dwarf Planet Pluto is the furthest from the Sun.No.Mars is the 4th planet from the sun.The furthest planet from the sun is Neptune.Previously the furthest was Pluto, however Pluto is no longer classified as a planet.
No, NASA (and now the whole world) does not classify Pluto as a planet. It is classified as a dwarf planet.
Pluto is now classified as a dwarf planet rather than an actual planet.
