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. In the theatrical Star Wars films, many scenes set on these planets and moons were filmed on location rather than on a sound stage. For example, the resort city of Canto Bight located on the planet Cantonica, seen in Star Wars: The Last Jedi (2017), was filmed in Dubrovnik, Croatia.

Star Wars canon astrography

The Star Wars galaxy contains several broad sub-regions. Their exact definitions fluctuated somewhat during the Legends continuity, but were later formally updated by the new canon continuity when Disney purchased Lucasfilm. The new canon map is broadly similar to the later versions of the Legends galactic map. As a general rule, most of the galaxy's wealth, power, and population are concentrated near the middle of the galactic circle – the "Core Worlds". The first major interstellar powers in the core are stated to have risen many millennia ago, gradually coalescing into the early Galactic Republic, with its capital at Coruscant. Waves of colonization (and conquest) by the Republic gradually spread outward from the Core, into the sparser systems at the galaxy's edge, such as Tatooine. Worlds of the Outer Rim are rich in raw resources but lack the population, infrastructure, or political power of the Core. Major galactic sub-regions are further divided into quadrants, sectors, etc., down to individual star systems and planets. The galaxy has at least two companion-satellite dwarf galaxies, one of which is known as the Rishi Maze, but they are very lightly settled or explored. The canon map depicts a top-down view of the galactic disk, with "north" as the side of the galactic center that Coruscant is located on. As the capital planet of the Republic and later the Empire, Coruscant is used as the reference point for galactic astronomy, set at XYZ coordinates 0-0-0. Standardized galactic time measurements are also based on Coruscant's local solar day and year. According to the updated Visual Dictionary series made by Pablo Hidalgo for the Sequel Trilogy, these are the general regions of the galaxy spreading outward from the Core: Apart from these broad regions radiating out from the galactic core, there are also several major galactic sub-regions of note: This official galactic astrography was later re-confirmed for the first time in on-screen, live-action dialogue in The Mandalorian. In the second season's fourth episode, "The Siege", a classroom is briefly shown on a planet in the Outer Rim, in which a lesson on galactic astrography is being taught by a protocol droid. The teacher not only lists off each of these major regions from the Visual Dictionary, but lists them in the exact same order, from the Outer Rim to the Core:

Star Wars canon planets and moons

The following list names prominent planets and moons from the Star Wars films or other canon media.

Star Wars Legends planets and moons

These are planets with multiple appearances in the Star Wars Expanded Universe, now rebranded as Star Wars Legends. The accompanying works were declared non-canon by Lucasfilm in April 2014, following its acquisition by The Walt Disney Company in October 2012.

Similarities to real-world planets

The discovery of exoplanets in the real-world universe gained pace in the early 21st century. In 2015, the US space agency NASA published an article which stated that many of the newly discovered astronomical bodies possessed scientifically confirmed properties that are similar to planets in the fictional Star Wars universe. Kepler-452b, a rocky super-Earth-type planet, is said to be similar to the Star Wars planet Coruscant. Likewise, the planets Kepler-16b and Kepler-453b, planets discovered orbitting binary stars probably resemble the desert world Tatooine. The hot, molten worlds of Kepler-10b and Kepler-78b are comparable to the volcanic planet Mustafar. OGLE-2005-BLG-390Lb, a cold, remote exoplanet, is like the ice planet Hoth. Kepler-22b, thought by scientists to be an ocean planet, is compared to the planet Kamino. According to NASA, there are also similarities to Alderaan and Endor in the real-world universe.

Solar System

Two non-canonical works also feature the real-life Solar System's planets. Monsters and Aliens from George Lucas (1993) contains a feature, presented as a clip from a gossip column, in which a pair of Duros are abducted by humans and taken to "Urthha" (Earth), where they create havoc by misunderstanding terrestrial objects and food. In issue #19 of the comic series Star Wars Tales (2004), the story "Into the Great Unknown" finds Han Solo and Chewbacca in the Millennium Falcon, fleeing the Imperial Navy. They jump to hyperspace without doing calculations and find themselves in the middle of our Solar System, overpassing Saturn, Jupiter, and Mars while decelerating and landing in Northern America. Han is killed by Native Americans, and a mourning Chewbacca leaves the Falcon to live in the trees, where the natives believe him to be a sasquatch. In an epilogue set 126 years later, archaeologist Dr. Jones and his sidekick Short Round, searching for the sasquatch, find the Falcon and Han's remains.
