The planet Alderaan

A planet, often called a world, was a large celestial body that was in orbit around a star.[1] Planets often had smaller bodies called moons that could be in orbit around the planet.[2] Many planets were habitable, meaning they were suitable for sentient beings to live on.[3] There were three known types of planets: terrestrial planets,[4] aquatic planets[5] and gas giants. Although gas giants were generally uninhabitable, floating constructs such as Cloud City could be built if the planet had a habitable layer.[3] A group of planets, moons,[2] and asteroids orbiting around a star were collectively called a star system.[6] The galaxy was home to thousands of star systems.[7] Although planets usually orbited only one sun, some, such as Tatooine[1] and Gatalenta, were located in systems that orbited multiple.[8] Certain planets were strong with the Force, such as Dathomir.[9]

When young Anakin Skywalker asked the Jedi Master Qui-Gon Jinn if all the stars in the galaxy had planets orbiting them, he answered that "most of them" do.[10]

"Homeworld" was a term used to describe the original home of a species,[11] organization,[12] or person.[13] For example, Ryloth was the homeworld of the Twi'lek species,[14] and the human species were believed to have originated on the planet Coruscant.[15]

It was possible to destroy a planet, although it required a massive superweapon, such as a Death Star.[4] It was also possible to turn a planet itself into a superweapon, as in the case of the First Order's Starkiller Base,[16] which was capable of destroying entire star systems, such as the ill-fated Hosnian system.[17]
