List of hypothetical Solar System objects information
This article is about hypothetical Solar System objects in astronomy. For hypothetical Solar System objects not recognized by science, see Planetary objects proposed in religion, astrology, ufology and pseudoscience. For other hypothetical astronomical objects, see Hypothetical astronomical object.
A hypothetical Solar System object is a planet, natural satellite, subsatellite or similar body in the Solar System whose existence is not known, but has been inferred from observational scientific evidence. Over the years a number of hypothetical planets have been proposed, and many have been disproved. However, even today there is scientific speculation about the possibility of planets yet unknown that may exist beyond the range of our current knowledge.
