Fictional planets of the Solar System
The fictional portrayal of the Solar System has often included planets, moons, and other celestial objects which do not actually exist in reality. Some of these objects were, at one time, seriously considered as hypothetical planets which were either thought to have been observed, or were hypothesized to be orbiting the Sun in order to explain certain celestial phenomena. Often such objects continued to be used in literature long after the hypotheses upon which they were based had been abandoned.
Other non-existent Solar System objects used in fiction have been proposed or hypothesized by persons with no scientific standing, while yet others are purely fictional and were never intended as serious hypotheses about the structure of the Solar System.
Vulcan
Vulcan was a hypothetical planet supposed to revolve around the Sun inside the orbit of Mercury, invoked to explain certain irregularities in Mercury's orbit. The planet was proposed as a hypothesis in 1859, and abandoned not later than 1915.- "Vulcan's Workshop", short story by Harl Vincent: a penal colony is located on Vulcan.
