Science fiction bibliographers E. F. Bleiler and Richard Bleiler, in the 1998 reference work Science-Fiction: The Gernsback Years, list various imaginary constituents of the pre-modern "science-fiction Solar System". Among these are planets between Venus and Earth, planets on the inside of a hollow Earth, and a planet "behind the Earth". [16]
The Fifth Giant may be hypothetical Planet Nine due to either the gravity of a nearby star or drag from the gaseous remnants of the Solar nebula which reduced the eccentricity of its orbit. A and B, two super-Earth (or even supergiant) planets theorized by Michael Woolfson as part of his Capture theory on Solar System formation. Originally the ...

Proper names of planetary systems often follow common themes – for example, the planets of the star Copernicus are named after European astronomers. Proper names for planets outside of the Solar System – known as exoplanets – are chosen by the International Astronomical Union (IAU) through public naming contests known as NameExoWorlds.
For instance, for a large portion of names ending in -s, the oblique stem and therefore the English adjective changes the -s to a -d, -t, or -r, as in Mars–Martian, Pallas–Palladian and Ceres–Cererian; [note 1] occasionally an -n has been lost historically from the nominative form, and reappears in the oblique and therefore in the English ...
Most extrasolar planets in fiction are similar to Earth—referred to in the Star Trek franchise as Class M planets—and serve only as settings for the narrative. [1] [2] One reason for this, writes Stephen L. Gillett [Wikidata] in The Greenwood Encyclopedia of Science Fiction and Fantasy, is to enable satire. [3]
The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk. There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets.
Following the acceptance of the Copernican model, planets were defined as objects which orbit the Sun. Since the Moon can be said to orbit the Earth, it was no longer regarded as a planet, but this is debated; see double planet.
