Exciting news everyone, a potential new dwarf planet has just been discovered in the Kuiper Belt at the edge of the Solar System. Called 2014 UZ224, it’s located beyond the orbit of Pluto, and may be one of a hundred such objects still undiscovered.
This particular object is thought to be about 530 kilometers (330 miles) across, compared to 2,374 kilometers (1,475 miles) for Pluto, one of the other five confirmed dwarf planets at the moment. The others are Ceres, Eris, Makemake, and Haumea. Another candidate, 2015 RR245, was announced earlier this year.
It was found by a team led by David Gerdes from the University of Michigan, as part of a larger map of galaxies called the Dark Energy Survey (DES). Using specialized computer software, they found the moving object about 13.7 billion kilometers (8.5 billion miles) from the Sun, about twice as far as Pluto. It completes an orbit in about 1,100 years.
According to NPR, it has taken two years to confirm the existence of 2014 UZ224. It is thought to be the third most distant known object in the Solar System.
We don’t know much else about the dwarf planet at the moment, aside from its size and orbital characteristics. But the discovery hints at even more objects in the outer Solar System, most notably Planet Nine, a world thought to be 10 times as massive as Earth. The search for this world continues.
The existence of 2014 UZ224 has been officially verified by the International Astronomical Union (IAU), but like 2015 RR245 before it, it’s not clear if it will be given official dwarf planet status yet. That will depend on a number of factors, including whether it is spherical. If so, though, it would be the smallest dwarf planet found so far.
Dwarf planet or not, our Solar System just got a little bit busier.
