List of Solar System objects most distant from the Sun in 2015

Positions of known outer Solar System objects.
The centaurs lie generally inwards of the Kuiper belt and outside the Jupiter trojans.

The orbit of Sedna, shown in red, with the dot marking its current location. Inside are the orbits of the giant planets of the Solar System, and that of Pluto in purple. Sedna will travel out nearly 1000 AU, taking almost six millennia to do so. It is currently less than 100 AU from the Sun.

This observation of Halley's Comet in 2003 at 28 AU from the Sun illustrates some of the difficulty in observing objects as they grow more distant.

The plutinos are the "spike" at 39 AU, whereas the classicals are between 42 and 47 AU, the twotinos are at 48 AU, and the 5:2 resonance is at 55 AU. Note this lists semi-major axis not current distance from the Sun (see Kuiper cliff)

This list of Solar System objects most distant from the Sun in 2015 is a list of bodies orbiting the Sun by their approximate distance from the Sun in the Earth year 2015 (as opposed to those with the greatest calculated aphelion in their orbit).

V774104 was announced in November 2015. It was heralded by many news outlets as "the most distant Solar System object", surpassing Eris (not counting space probes and long-period comets).[1]

Another very distant body is Sedna, discovered in November 2003. Although it takes over 10,000 years to orbit, it will slowly get closer over the next 60 years to its perihelion.[2]

Because all these objects are moving, the list changes significantly over time. In particular, some objects are in-bound and some are out-bound. It is hard to see comets at the longer distances. It is usually their big comas that allow them to be detected more easily when they get heated by the Sun.

List

Distances are in astronomical units (AU, Sun–Earth distances); listed are current (as of 2015) locations, not future min or maxes. There are also known comets at great distances, but they are currently too faint to be observed. This is a list based on objects discovered up to this year:
