Only discovered a dwarf planet farther away than Neptune

A team of astronomers, including researchers from the University of British Columbia (Canada), have discovered a new dwarf planet farther away than Neptune in the Solar System. This planet is called the Dubbed 2015 RR245 by the International Astronomical Association.

Dubbed 2015 RR245 has a diameter of about 700km, has a long trajectory from the Sun 120 times larger than Earth. This is a remote neighbor of us.

Astronomers are expanding to search for dwarf planets in the Kuiper belt (also known as the Kha Y belt). RR245 is found by scientists, as part of the Solar System's Out-of-Home Survey (OSSOS). It can be said that this is the largest OSSOS finding so far, with more than 500 bodies outside Hai Vuong crystal identified by this investigation.

"Frosty planets other than Neptune track giant planets formed and then move away from the Sun." They show us how the graft is in the history of our solar system , 'said Michele Bannister, a researcher from the University of British Columbia, Canada. "However, most of these ice planets are very small and faint. This will be interesting if we find a large planet and are bright enough that we can conduct detailed research ''.

It will take about 700 years for RR245's large long orbit to reach the Sun's orbit. Researchers say it is traveling in the nearest area. This region may be found within 5 billion km of the Sun around 2096.

That's after the planet has spent hundreds of years more than 12 billion kilometers from the Sun. However, the team of researchers still needs much evidence to accurately determine RR245's movement, as we can only observe a very small part of its distant history.

Scientists believe that there are many dwarf planets in our Solar System, but most of them are destroyed or ejected when larger planets in the Solar System move to their current positions. RR245 is one of those "surviving" over this period - like Ceres, Pluto, Haumea, Makemake, and Eris - all of which are called dwarf planets by the International Astronomical Society - in tens of thousands of stars farther than Hai Vuong.

For the first time, scientists discovered the dwarf planet was in February, found by astronomer JJ Kavelaars from the Canadian National Research Council through OSSOS data recorded and September 2015.

"It appears on the screen ," Bannister said, "which is a light point that moves quite slowly, so it must be more than twice the distance of Neptune from the Sun".

The team predicts that RR245 may be one of the largest worlds discovered farther away than Neptune , as dwarf planets have been established on the map. However, the advent of the Giant Telescope in the next decade can help us detect planets farther away.

"OSSOS is designed to map the orbital structure outside the Solar System to decipher its history," explained Brett Gladman, a researcher at Columbia University, Canada. "Because it was not designed to detect dwarf planets, we were very happy when OSSOS found a planet with such an interesting trajectory."

But, in addition to helping us map out the Solar System, its discovery of dwarf planets and its geological components helps us understand more about the universe's past in our galaxy. .

" Their movement generates the Solar System ," astrophysicist Pedro Lacerda from Belfast University in Northern Ireland, who did not participate in the discovery of RR245 in The Guardian, "" You have "It is possible to find something similar to fossils, which is a testament to the long-standing existence of creatures."

This finding has not yet been officially announced, so we are still waiting for more details from the researchers, but the RR245 has been officially recognized by the International Astronomical Society.
