The most distant known object in our solar system was recently discovered by astronomers.

Scientists with the International Astronomical Union’s Minor Planet Center announced the discovery of the object dubbed "Farout" on Monday.

Object 2018 VG18 was first observed on Nov. 10 by Carnegie Institute of Science's Scott S. Sheppard, the University of Hawaii’s David Tholen and Northern Arizona University’s Chad Trujillo using the Japanese Subaru 8-meter telescope located on Mauna Kea in Hawaii.

A second observation in early December via the Magellan telescope at the Las Campanas Observatory in Chile offered astronomers more details on the object that is over three-and-a-half times more distant from the sun than the solar system’s most-famous dwarf planet, Pluto.

While large enough to be a possible dwarf planet, astronomers do not believe the object is large enough to be Planet X — sometime referred to as Planet Nine — a suspected ninth planet in the solar system, according to the press release.

The object is so far away that astronomers say a trip around the sun on 2018 VG18 might take up to 1,000 Earth years, but it could take some time before that is definitively determined.

“Because 2018 VG18 is so distant, it orbits very slowly, likely taking more than 1,000 years to take one trip around the Sun," Tholan said in the press release.

The object appears to be pinkish in color and approximately 310 to 372 miles in diameter, the astronomers note.

“This would make it a dwarf planet. The color of the object is pinkish to red in color, which suggests it has an icy surface," Sheppard told Gizmodo. "Ice usually turns reddish in color after being irradiated for long periods of time from the Sun’s radiation.”

The team of astronomers say the discovery can help scientists understand what is happening in the solar system’s outer reaches.

“This discovery is truly an international achievement in research using telescopes located in Hawaii and Chile, operated by Japan, as well as by a consortium of research institutions and universities in the United States,” concluded Trujillo. “With new wide-field digital cameras on some of the world’s largest telescopes, we are finally exploring our Solar System’s fringes, far beyond Pluto.”
