Planet (Earth-2356)

"Well, if there's a bright center of the universe, you're on the planet that it's farthest from."

- Luke Skywalker to C-3PO

A planet, often called a world, is a large celestial body that is in orbit around a star. Planets often have smaller bodies called moons that can be in orbit around the planet. Many planets are habitable, meaning they are suitable for sentient beings to live on. There are three known types of planets: terrestrial planets, aquatic planets and gas giants.

Although gas giants are generally uninhabitable, floating constructs such as Cloud City can be built if the planet has a habitable layer. A group of planets, moons, and asteroids orbiting around a star are collectively called a star system. The galaxy is home to thousands of star systems. Although planets usually orbit only one sun, some, such as Tatooine and Gatalenta, are located in systems that orbited multiple. Certain planets are strong with the Force, such as Dathomir.

When a young Anakin Skywalker asked the Jedi Master Jiraiya if all the stars in the galaxy had planets orbiting them, he answered that "most of them" do.

"Homeworld" is a term used to describe the original home of a species, organization, or person. For example, Ryloth is the homeworld of the Twi'lek species, and the Human species is believed to have originated on the planet Coruscant.

It is possible to destroy a planet, although it requires a massive superweapon, such as a Death Star. It is also possible to turn a planet itself into a superweapon, as in the case of the First Order's Starkiller Base, which was capable of destroying entire star systems.
