The International team of astronomers has discovered a new dwarf planet in our Solar System beyond Neptune that circles the Sun in a dramatically wide orbit.
The International Astronomical Union (IAU) dubbed it ‘2015 RR245’, about 700 kilometres in diameter, its elongated orbit sends it out some 120 times further from the Sun than Earth.
Astronomers revealed ‘RR245’ stands out due to its size and orbit in the Kuiper belt.
Scientists also found out, of more than 500 trans-Neptunian objects identified, it is the largest OSSOS (Outer Solar System Origins Survey) discovery to date.
The team of researchers admits there’s still a lot to be confirmed about RR245’s precise movements, as they’ve only been able to observe just a tiny fraction of its epic loop.
But apart from this newly discovery ‘RR245’, is now included the ranks of other survivors such as Ceres, Eris, Pluto, Makemake, and Haumea, which all been recognised as dwarf planets by the IAU amidst the tens of thousands of much smaller objects beyond Neptune.
Brett Gladman of the University of British Columbia, Canada said, “While OSSOS is not designed to efficiently detect dwarf planets, we we’re delighted to have found one on such an interesting orbit.”
Meanwhile, Astrophysicist Pedro Lacerda from Queen’s University Belfast in Northern Ireland, noted that the discovery of these dwarf planets and their unique geological composition helps understand more about the cosmic past in our galaxy.
