TheseSolar System minor planets are the furthest from theSun as of January 2026^[update]. The objects have been categorized by their approximate distance from the Sun on that date, and not by the calculatedaphelion of their orbit. The list changes over time because the objects are moving in their orbits. Some objects are inbound and some are outbound. It would be difficult to detect long-distance comets if it were not for theircomas, which become visible when heated by the Sun. Distances are measured inastronomical 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 includenear-parabolic comets of which many are known to be currently more than 100 AU (15 billion km) from the Sun, but are currently too far away to 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 withobservation arcs less than several years often have poorly constrained orbits. Particularly distant objects take several years of observations to establish a crude orbit solution before being announced. For instance, the most distant known trans-Neptunian object2018 AG37 was discovered byScott Sheppard in January 2018 but was announced three years later in February 2021.^[1]

One particularly distant body is90377 Sedna, which was discovered in November 2003. It has an extremely eccentric orbit that takes it to an aphelion of 937 AU.^[2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes toperihelion at a distance of 76 AU from the Sun.^[3] Sedna is the largest knownsednoid, a class of objects that play an important role in thePlanet Nine hypothesis. The discovery of2017 OF₂₀₁ challenges the existence of the hypothetical Planet Nine as its orbit is anti-aligned to the calculated orbit of Planet Nine. It is suggested that the hypothetical planet would have ejected2017 OF₂₀₁ from its present-day orbit over times scales of less than 100 million years, though it could be in a temporary orbit.^[4][5]

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

This is a list of known objects at heliocentric distances of more than 80 AU. In theory, theOort cloud could extend over 120,000 AU (2 ly) from the Sun.
