The planetoid, nicknamed Farfarout, was first discovered in 2018. Now astronomers have collected
Farfarut will receive an official name afterhow its orbit will be better defined over the next few years. It was discovered with the 8-meter Subaru telescope located at the summit of Mauna Kea in Hawaii. Telescopes Gemini North and Magellan helped to calculate the orbit.
Farfarut's average distance from the Sun is132 astronomical units (AU). Let us recall that 1 au. Is the distance between the Earth and the Sun. For comparison, Pluto is only 39 AU. from the sun. The newly discovered object has a very elongated orbit, which puts its farthest orbit at 175 AU.

The lower left corner of the graph shows the distances to planets, dwarf planets, candidates for dwarf planets and the Far Abroad from the Sun in astronomical units (AU). One au equal to the average distance of the Earth from the Sun. Farfarut is located at a distance of 132 AU. from the sun. Credit: NOIRLab / NSF / AURA / J. da Silva
One revolution of Farfarut around the Sun takes a millennium. Because of this long orbit, it moves very slowly across the sky, and it takes several years of observation to accurately determine its trajectory.

Farfarut is very dull, and based on itsbrightness and distance from the Sun, scientists estimate its size to be about 400 km across. This puts it on the lower edge of a dwarf planet. Scientists speculate that it is an ice-rich object.
