Farout: Scientists spot solar system's farthest known object


But even that is just a tiny baby space distance, compared to how far out from the Sun the dwarf planet informally known as Farout is. For comparison, Pluto is roughly 34 astronomical units (or AU) from the Sun, and Eris, the previous "farthest known object in the solar system" is 96 AU from the Sun.

The observations were reported today in a circular distributed by the International Astronomical Union's Minor Planet Center.

The object, a pink dwarf planet called 2018 VG18 and nicknamed "Farout", lies more than 100 times further from the sun than the Earth is. The discovery was made by Carnegie's Scott S. Sheppard, the University of Hawaii's David Tholen, and Northern Arizona University's Chad Trujillo. This includes The Goblin, which was discovered at about 80AU and has an orbit consistent with it being influenced by a planet of Earth's size.

Now, scientists have identified the most distant body ever observed in our Solar System. - Scott Sheppard, Carnegie Science Institute.

"Planet X needs to be several times larger than Earth in order to gravitationally push the other smaller objects around and shepherd them into similar types of orbits", explained Sheppard.

Farout was spotted by the Japanese Subaru telescope in Hawaii on November 10 by Shepard and a few colleagues, according to a statement on Carnegie Institution for Science's site.

As its official name is hard to remember, 2018 VG18, its discoverers nicknamed it Farout.

Their finding was confirmed by a telescope in Chile.

The sun's gravity decreases with distance.

The team say Farout's brightness suggests it is about 500km (310 miles) wide, and it is probably spherical.

Its pink shade indicates an ice-rich object. At that distance, it could take more than 1,000 years to orbit the sun. What was once considered a vast, cold emptiness is now known to be the home of several objects. The telescope, made the first recordings of the "Farout", and from Japan, with a consortium of universities in the U.S. and several research facilities.

"This discovery is truly an worldwide 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", Trujillo said in the press release. A new wide-angle digital cameras are on some of the world's largest telescopes. "Farout" is located at approximately 120 astronomical units (AU).

The findings demonstrate that even though astronomers are now routinely discovering planets orbiting different stars, there are still planet-sized unfamiliar objects in our very own Solar System. It took NASA's New Horizons spacecraft nine years to get to Pluto, and Farout is about 3.5 times farther away than Pluto, so it would take about 31 years for a spacecraft to reach Farout. Preliminary research suggests it's a round, pinkish dwarf planet. As part of this search, they have discovered space bodies nicknamed The Goblin and Biden. Their work has been focused on looking for the suspected Planet X, sometimes known as Planet 9.
