List of Solar System objects by greatest aphelion

The orbit of Sedna lies well beyond these objects, and extends many times their distances from the Sun
The orbit of Sedna (red) set against the orbits of outer Solar System objects (Pluto's orbit is purple).

This is a list of Solar System objects by greatest aphelion or the greatest distance from the Sun that the orbit takes it. For the purposes of this list, it is implied that the object is orbiting the Sun in a two-body solution without the influence of the planets or passing stars. The aphelion can change significantly due to the gravitational influence of planets and other stars. Most of these objects are comets on a calculated path and may not be directly observable.[1] For instance, comet Hale-Bopp was last seen in 2013 at magnitude 24[2] and continues to fade, making it invisible to all but the most powerful telescopes.

The maximum extent of the region in which the Sun's gravitational field is dominant, the Hill sphere, may extend to 230,000 astronomical units (3.6 light-years) as calculated in the 1960s.[3] But any comet currently more than about 150,000 AU (2 ly) from the Sun can be considered lost to the interstellar medium. The nearest known star is Proxima Centauri at 271,000 AU which is 4.22 light years,[4] followed by Alpha Centauri at about 4.35 light years away according to NASA.[4]

Comets are thought to orbit the Sun at great distances, but then be perturbed by passing stars and the galactic tides.[5] As they come into or leave the inner Solar System they may have their orbit changed by the planets, or alternatively be ejected from the Solar System.[5] It is also possible they may collide with the Sun or a planet.[5]

Comets with greatest aphelion (2 body heliocentric)

The exact furthest distance from the Sun (aphelion) can be very different depending on the object's position in its orbit, as well as the epoch. An incoming asteroid could be slowed down by Jupiter, making its orbit closer to the Sun. The aphelion distance for heliocentric orbits (only taking into account the present location of the Sun as the orbited mass) can be highly inaccurate for objects with an orbital eccentricity approaching 1 (a hyperbolic orbit not bound to the Solar System) especially when the orbit is calculated while the object is near its closest point to the Sun and has not left the planetary region of the Solar System, where it passes closest to planets which could alter its orbit significantly. Barycentric solutions are more accurate because they account for the combined gravity of the Sun and the most massive planet Jupiter. An epoch of 2200 has all of these objects well outside of the planetary region of the Solar System. In 2200, comet C/2012 S4 will be 178 AU (27 billion km) from the Sun.

It should be noted that the exact position of Planet Nine is poorly known, so some comets might have been slightly perturbed by it. However, statistically only 0.17% of distant comets should pass less than 100 AU from planet Nine, and only 0.0017% less than 10 AU.

Distant comets with long observation arcs and/or barycentric

Comet West in 1976

Examples of comets with a more well-determined orbit. Comets are extremely small relative to other bodies and hard to observe once they stop outgassing (see Coma (cometary)). Because they are typically discovered close to the Sun, it will take some time even thousands of years for them to actually travel out to great distances. The Whipple proposal might be able to detect Oort cloud objects at great distances, but probably not a particular object.

Minor planets

A large number of trans-Neptunian objects (TNOs) – minor planets orbiting beyond the orbit of Neptune – have been discovered in recent years. Many TNOs have orbits with an aphelion (farthest distance to the Sun) far beyond Neptune's orbit at 30.1 AU. Some of these TNOs with an extreme aphelion are detached objects such as 2010 GB174, which always reside in the outermost region of the Solar System, while for other TNOs, the extreme aphelion is due to an exceptionally high eccentricity such as for 2005 VX3, which orbits the Sun at a distance between 4.1 (closer than Jupiter) and 2200 AU (70 times farther from the Sun than Neptune). The following is a list of TNOs with the largest aphelion in descending order.[14][15]
