A planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with the planetary system revolving around it, including Earth, forms the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems.
As of 1 November 2022, there are 5,246 confirmed exoplanets in 3,875 planetary systems, with 842 systems having more than one planet. Debris disks are also known to be common, though other objects are more difficult to observe.
