These are lists of planets. A planet is a large, rounded astronomical body that is neither a star nor its remnant. 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.
As of 8 October 2026, there are 6,445 confirmed exoplanets in 4,834 planetary systems, with 1,070 systems having more than one planet. There are an additional 1,977 potential exoplanets from the Kepler space telescope's first mission yet to be confirmed, as well as 975 from its "Second Light" mission and 4,823 from the Transiting Exoplanet Survey Satellite (TESS) mission.
