Astronomers confirm the status of the most distant known object in the solar system

Scientists have confirmed that they have found the most distant known object in the solar system FarFarOut, a large chunk of rock discovered in 2018 at a colossal distance of about 132 astronomical units from the Sun, has officially achieved this status.

The object is about 400 kilometers in diameter – in fact, it falls within the lower limit of the group of dwarf planets. Initial observations show that its average orbital distance is 101 astronomical units – 101 times the distance between the Earth and the Sun.

Since Pluto has an average orbital distance of about 39 astronomical units, FarFarOut is indeed a very distant body. It has been given the provisional designation 2018 AG37, and its own name in accordance with the recommendations of the International Astronomical Union has not yet been determined, so it is still called an informal nickname.

Its orbit is not an even circle around the Sun, but a very elongated oval. After careful observation, scientists have calculated that the ellipse extends 175 astronomical units and approaches 27 astronomical units inside Neptune’s orbit.
