This is a list of fictional planets and moons from the Firefly / Serenity fiction. In the show, they are also referred to simply as "worlds". During the short television run of the Firefly series, it was not made clear whether the planets and moons depicted were located in one planetary system or many (however, creator Joss Whedon, as well as all licenced products, confirm that there is no faster-than-light travel in the Firefly universe). The opening narration of the film makes it clear that the planets and moons are in one system with "dozens of planets and hundreds of moons." This is supported by production documents published in Serenity: The Official Visual Companion. Still, there is debate over whether all are located in the same planetary system, as maps shown in the film appear to be contradictory. Possibly, the system is a form of star cluster, since some of the aforementioned maps include multiple stars. This would also be required to supply enough sunlight for this large list of planets. All of the following bodies were terraformed and made to have a standard gravity in order to be capable of supporting human life.
The number of terraformed worlds is never mentioned in the series though in a deleted scene from the episode "Our Mrs. Reynolds", Captain Malcolm Reynolds mentions to the character Saffron that there are "more than 70 earths spinning in this galaxy and the meek have inherited nary a one." The scene was cut because it was too long but its information regarding the number of worlds can be taken as canon. However, the opening narration of the film Serenity gives us a brief history of the Firefly universe and mentions; "Earth that was could no longer sustain our numbers, we were so many. We found a new solar system, dozens of planets and hundreds of moons."
During the movie Serenity, the planet Miranda is (wrongly) referred to as a 'black rock,' a planet where no life exists or is possible. This seems to imply that such a thing exists and there is a term for it. In fact, a generic explanation (terraforming didn't take) is offered to explain it, indicating that this simply happened some times while the terraforming process was occurring.
Although technically they are all part of the Alliance, the border planets and moons are mostly self-governed.
Ariel is a central planet of the Union of Allied Planets. It is home to a major medical center (named Saint Lucy's) of the Alliance's solar system. The majority of the action of the episode "Ariel" occurs on this planet. Ariel could be named after one of Uranus' moons in the system of "Earth that was," which gets its name from the sprite in William Shakespeare's The Tempest. The crew of Serenity arrives on this planet for a heist on an advanced medical facility.
Bellerophon, seen in the episode "Trash", is an Alliance moon and home to the wealthy. It has both a large ocean and an empty area of desert climate, complete with canyons, rock and sand. Isis Canyon is pointed out as the most deserted spot on the world. Bellerophon Estates, large self-contained estates that hover above the moon's ocean, are described as having "gracious living, ocean views and state-of-the-art security." Durran Haymer, a collector of priceless Earth That Was artifacts, lives in Bellerophon Estates. The planet is named after a hero in Greek mythology. "Bellerophon" is also the unofficial name of 51 Pegasi b, the first extrasolar planet to be discovered.
Hera is an Earth-like planet with important significance to the Unification War. Serenity Valley is located here, where the the Independent Faction experienced a crushing defeat at the hands of the Alliance. First mentioned in the episode "Serenity". Hera is named after a goddess in Greek mythology, Zeus' wife and sister.
Higgins' Moon is a moon where the primary commercial activity is mud farming which is performed by indentured servants called "mudders". The mud is exported offworld and used in the manufacturing of ceramic components. The bulk of the population is impoverished. The moon appears to be owned by a magistrate named Higgins. Jayne became a folk hero to the mudders in the town of Canton due to his role in a botched heist about four years before the time of the Firefly series. The crew visits Higgins' Moon in the episode "Jaynestown."
Jiangyin is a border planet located 3 weeks away from Persephone, and also nearby Greenleaf. Alliance law is known to be upheld here. The crew of Serenity sells a cargo load of cattle here in the episode "Safe". The planet is most likely named after a city in China's Jiangsu province along the Yangtze River.
Osiris is a wealthy core planet where Simon Tam attended medical school and worked as a trauma surgeon, mentioned in the episode "Serenity". Most likely the location of the Tam Family estate shown in various flashbacks in the episode "Safe". Named after the Ancient Egyptian god of life, death, and fertility, "Osiris" is also the unofficial name of HD 209458 b, the first extrasolar planet to be discovered by the transit method. Some people who have misunderstood the nature of the visions River experiences in Serenity may believe that Osiris is also the location of the classroom where young River Tam attends school, as shown in the feature film. Of course, this classroom is actually located on Miranda, and River experiences it in various states as the source and nature of her visions become clear.
Persephone is a civilized planet with heavily stratified societal structure. The Eavesdown Docks are located here, a commercial port and Badger's base of operations. The Serenity crew lands here periodically to resupply and pick up work. Simon and River Tam, Shepherd Book and the Alliance villain Dobson were picked up here in the episode "Serenity". Book had been living on Persephone at the Southdown Abbey. The planet was also the site of a swordfighting duel between Malcolm Reynolds and Atherton Wing in the episode "Shindig". Persephone's name comes from Greek mythology as the name of the "Queen of the Underworld".
St. Albans is an icy world, and Tracey's home planet. Located about two days away from the Space Bazaar Sky Plex. There is apparently a single Federal Station located somewhere on the planet, reasonably close to a huge gorge through which Serenity flies in an attempt to outrun an Alliance gunship. Tracey is brought back to this planet in the episode "The Message".
Whitefall is the fourth moon of Athens, a large percentage of which is owned by a woman named Patience. Whitefall is said to not be civilization "in the strictest sense." The crew visits Whitefall hoping to sell their cargo to Patience in the episode "Serenity". According to the RPG, a Blue Sun facility is rumored to be underneath one of the mountains. A security outpost on the planet was later seen in the film Serenity.
Beaumonde is a fairly wealthy planet, relatively close to certain border worlds. The planet is known to have factories and ranches. The Serenity crew arrives here after their heist on Lilac, to share part of their earnings with the brothers Fanti and Mingo. At the bar called Maidenhead, which was chosen for these dealings, they discover River's Alliance-conditioned fighting abilities. This occurs during the Serenity movie. About seven months earlier, the crew was headed for Beaumonde in the episode "Our Mrs. Reynolds". Beaumonde roughly translated from French means "Beautiful World."
Haven is the home of Shepherd Book, who left the crew during the events of the comic book series titled Serenity: Those Left Behind, and where he resided in the movie. It was also a place of refuge for the Serenity crew. In the novelization of the film, it is revealed that Haven is a mining planet which is often used as a hiding place for those running from the law (for a fee) and is where some smugglers or criminals decide to settle down.
Lilac is a border world probably near Reaver territory. From space it appears to have a lilac color, which presumably it was named for. The Serenity crew land on Lilac to rob a bank holding an Alliance payroll.
Miranda is the name of a planet located beyond Reaver territory.[1] It was home to an Alliance colony with a population of 30 million. The Alliance experimented on the population to find a way to make people more controllable. However the experiments failed: 99.9% of the population became so passive that they essentially lost the will to live. The opposite effect was observed in the remaining 0.1% of the population, who became extremely aggressive and butchered the Alliance scientists in charge of the experiments. This tenth of a percent of the population escaped to become the Reavers. The Alliance tried to cover up what had happened on the planet by creating a story that the colony was lost due to failure in the environmental changes caused during the planet's terraforming process. Writer/Director Joss Whedon says in the DVD commentary that the naming was based on the character from The Tempest. The irony is that the Shakespearean character is most noted for the lines, "O, wonder! How many goodly creatures are there here! How beauteous mankind is! O brave new world, That has such people in't!" Like other planets in the Firefly universe, it also shares its name with a moon in our solar system, in this case, a moon of Uranus.
