context_page_description: 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. For instance, comet Hale-Bopp was last seen in 2013 at magnitude 24 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 as calculated in the 1960s. But any comet currently more than about 150,000 AU 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, followed by Alpha Centauri at about 4.35 light years away according to NASA.
  Comets are thought to orbit the Sun at great distances, but then be perturbed by passing stars and the galactic tides.
