Since Pluto is no longer acknowledges the real planet, has several times found “dwarf planet” Pluto have similar orbits beyond Neptune. Dwarf planet is a term for a planet that does not meet the third criterion of three planets criteria set by the International Astronomical Union.
One interesting thing is that apparently in addition to the dwarf planet Pluto, beyond the orbit of the planet Neptune lies a giant orbit space contains many objects that scientists have nicknamed him the Kuiper Belt. The Kuiper Belt is an orbit of ice in which there are few objects of space that has been identified by scientists as a dwarf planet, like Eris, Haumea, Makemake, Sedna, Quaoar, 2007 OR10, and of course Pluto which has been first discovered in 1930 by Clyde W. Tombaugh. Even recently identified a new dwarf planet that orbits super far exceeds other dwarf planets that travel is about 700 Earth years. Planet is still named interim RR245 2015 is estimated to have a diameter of only 700 kilometers, there are still much smaller than the dwarf planet Pluto has a diameter of 2371 km.
The discovery of the dwarf planet 2015 RR245 which was first identified in February, is one of the results of surveys, titled Outer Space Solar System Origins Survey (Ossos). Ossos so far been detected at least 500 space objects in the Kuiper Belt Area. However new RR245 2015 are identified as a dwarf planet. Astronomers will continue to observe planets that orbit will reach its closest distance to the sun in the year 2096, in order to obtain data that is more accurate.
