List of Solar System objects most distant from the Sun

These Solar System minor planets are the farthest from the Sun as of March 2020. The objects have been categorized by their approximate heliocentric distance from the Sun, and not by the greatest calculated aphelion of their orbit. The list changes over time because the objects are moving. Some objects are inbound and some are outbound. It would be difficult to detect long-distance comets if it weren't for their comas, which become visible when heated by the Sun. Distances are measured in astronomical units (AU, Sun–Earth distances). The distances are not the minimum (perihelion) or the maximum (aphelion) that may be achieved by these objects in the future.

This list does not include near-parabolic comets of which many are known to currently be more than 100 AU (15 billion km) from the Sun, but are too far away to currently be observed by telescope. Trans-Neptunian objects are typically announced publicly months or years after their discovery, so as to make sure the orbit is correct before announcing it. Due to their greater distance from the Sun and slow movement across the sky, trans-Neptunian objects with observation arcs less than several years often have poorly constrained orbits. Particularly distant objects discovered in 2020 may only be announced in 2022 or later.

Noted objects

One particularly distant body is 90377 Sedna, which was discovered in November 2003. Although it takes over 10,000 years to orbit, during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun.[1] Sedna is the largest known sednoid, a class of objects that play an important role in the Planet Nine hypothesis.

Pluto (30–49 AU, about 34 AU in 2015) was the first Kuiper belt object to be discovered (1930) and is the largest known dwarf planet.

Known distant objects

This is a list of known objects at heliocentric distances of more than 60 AU. In theory, the Oort Cloud could extend over 120,000 AU (2 ly) from the Sun.
