The fictional universe of the Star Wars franchise features multiple planets and moons. While only the feature films and selected other works are considered canon to the franchise since the 2012 acquisition of Lucasfilm by The Walt Disney Company, some canon planets were first named or explored in works from the non-canon Star Wars expanded universe, now rebranded Star Wars Legends.

These are planets with multiple appearances in the Star Wars expanded universe, now rebranded Star Wars Legends. The accompanying works were declared non-canon by The Walt Disney Company following its 2012 acquisition of Lucasfilm.

NASA reported in 2015 that some planets in the fictional Star Wars universe possess similarities to scientifically confirmed exoplanets in the real-world universe: Coruscant (Earth-like world) is like Kepler-452b; Tatooine (world with twin suns) is like Kepler-16b and Kepler-453b; Hoth (cold world) is like OGLE-2005-BLG-390Lb; Mustafar (hot molten world) is like Kepler-10b and Kepler-78b; and Kamino (ocean world) is like Kepler-22b. There are also similarities to Alderaan (Princess Leia's home planet) and Endor (the Ewoks' forested exomoon) in the real-world universe, according to NASA.
