there are 4 others
Well, Pluto isn't recognized as a planet, but as a dwarf planet. Also, there are other dwarf planets, but they are more like really big comets than they are planets.
Eris is a dwarf planet that exists beyond Pluto
for two reasons:Pluto is not a planet. It is a dwarf planet.There are 3 more dwarf planets that orbit the Sun beyond Pluto.
When a few dwarf planets had been discovered, it was found they have orbits which are significantly more elliptical and/or more highly inclined to the ecliptic than the eight main planets. Pluto had more in common with the new discoveries so a new class of dwarf planets was started, and Pluto was put into it.
Their are more than 3 dwarf planets. Some of the famous ones are Pluto and Ceres.the three dwarf planets are Ceres Pluto and ErisThe three dwarf palnets are Pluto, Eris, and CeresPluto, Eris, and Ceres
Since Pluto was down graded to a Dwarf planet in 2006, our solar system only has 8 major planets orbiting the Sun. However there are a few more Dwarf planets outside the orbit of Pluto that are being considered for Dwarf Planet status.
Pluto and the dwarf planets
Pluto, Ceres, Eris, Sedna and Makemake are the five "dwarf planets" designated so far. Ceres, Pluto, Haumea, Makemake and Eris are currently the five bodies classed as dwarf planets, but there are further candidates that could be classed as dwarf planets once more information on their shape has been uncovered.
These are currently defiend as dwarf planets: Ceres Pluto Haumea Makemake Eris There are some other ateroids that are currently considered candidates for dwarf planet status, however further study is required to confirm.
Mars, Pluto ( a dwarf planet )... A spaceship is going to Pluto and learn more about the planet by taking pictures.
No. There are more dwarf planets, but as of the reclassification by the International Astronomical Union in 2006, there are only 8 planets, not including Pluto.
Ceres, Eris (formerly UB313) and Pluto are dwarf planets. Charon is Pluto's largest moon. The change in planetary classification was made in August, 2006 by the International Astronomical Union (IAU), and the dwarf planets are defined as non-satellite Sun-orbiting bodies that do not "clear out their (planetary) neighborhood" as major planets do. As of January, 2009, the five dwarf planets include these 3 plus 2 more Kuiper Belt Objects, Haumea and Makemake.
