Neptune is the 8th planet from the Sun, the fourth largest planet by size and the third by mass. Neptune was actually observed by Galileo Galilei on at least two occassions in 1612 and 1613, but did not realize that it was a planet, mistaking it for a star. In 1845, John Couch Adams and Urbain Le Verrier indpendently calculated that there should be another planet based upon perturbations of the orbit of Uranus. Le Verrier sent a letter with his findings to Johann Gottfried Galle who was then the first observer of Neptune and recognized it for what it is.
Neptune in Orbiter
Neptune has been a part of the Orbiter family of bodies at least since the release of Orbiter 2001. In the 2001 version, Neptune had no moons, but 14 moons have been added in later releases of Orbiter or as a part of add-ons.
In Orbiter 2002, the orbital parameters were moved from Neptune.cfg to the module Vsop87.dll. In neptune.zip, Neptune's rings were added.
