It has the largest known orbit for a planet and needs 700 years to orbit the Sun
An international team of astronomers announced today the existence of a new dwarf planet in the solar system whose orbit has its farthest point to 19.000 million kilometers from the sun.
Baptized provisionally as RR245, it has a diameter of about 700 kilometers and one of the largest orbits to a dwarf planet, reported the National Center for Scientific Research (CNRS ), who participated in the discovery.

“It is so far to sunlight costs 18.5 hours to reach it”
“It is so far to sunlight costs 18.5 hours to reach it,” he said the agency EFE researcher Jean-Marc Petit.
the RR245 was discovered in the Kuiper belt using the telescope Canada-France-Hawaii in Maunakea (Hawaii) and its size and brightness allow to be analyzed in detail and help to reconstruct the history of our solar system.
An expert from the National Research Council of Canada (CNRC), who also participated in the study, first detected in February to from images taken in September 2015.
the planet completes its orbit in 700 years -with which exceeds the orbital period of the other planets and has only been observed during one of those years, so scientists warn that still do not know where it comes from or how it will evolve its orbit in the future.
the team points out that the vast majority of dwarf planets like RR245 were destroyed or expelled from Solar system during caused chaos when the giant planets moved to stand in their current positions.
the latter is “one of the few dwarf planets that has survived to this day, along with Pluto and Eris, the largest known dwarf planets, “they said in the CNRS, glad detected” in such an improbable orbit “and the possibilities of study that opens.
with the addition of the RR245 the solar system and has six dwarf planets, a definition that was coined in 2006 when Pluto was demoted from planet category, then re-enter as a dwarf. Then, Ceres, Eris, Makemake and Haumea joined -the three last discovered in 2005 and now the RR245. In addition, the dwarf planets are integrated into the eight planets known
Then, the solar system is now made up of 14 planets according to their proximity to the sun, are in the following order:. Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, Eris and RR245.
But it is very likely that the bill does not end there, as there are at least 12 celestial objects waiting to enter the category of dwarf planets and depend on further research to confirm finished.
