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. Featured in Firefly.
Haven, a moon of Deadwood, the seventh planet orbiting the Blue Sun. 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. ISSA is known to have a firm hold on this planet though it is a common place to find Brown Coat dealings
Hera is an Earth-like planet with important significance to the Unification War. It orbits the protostar Murphy, which is the fourteenth planet orbiting the star Georgia.2 Serenity Valley is located here, where the Independent Faction experienced a crushing defeat at the hands of the Alliance. Hera is named after a goddess in Greek mythology, Zeus’ wife and sister.
Higgins’ Moon orbits Harvest, the fourth planet orbiting the Red Sun, where the primary commercial activity is mud mining which is performed by indentured workers called “mudders”. The mud is exported offworld and used in the manufacturing of ceramic components. The bulk of the population are impoverished and/or indentured workers. 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.
Jiangyin is a border planet located three weeks away from Persephone, and also nearby Greenleaf. It is the first planet orbiting the Red Sun and is the capital world of that system. 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.
Lilac is a moon of New Canaan, the second planet orbiting the Blue Sun and is 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. Lilac is at times roughly ten hours from Beaumonde as stated by Mal.
Miranda is the name of a planet located beyond Reaver territory.1 It orbits the protostar Burnham, the eighth and final planet in the Blue Sun system.2 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 with “G-23 paxilon hydrochlorate”, or “Pax”, 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 terraforming equipment. This information getting out is what sparks the Brown Coats into levying a war against the CORE
Osiris, the seventh world orbiting the White Sun, 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”.

The Eavesdown Docks are located here, a commercial port and Badger’s base of operations. Book had been living on Persephone at the Southdown Abbey.

St. Albans, the fifth planet orbiting the Red Sun, is an icy world, and Tracey’s home planet. Located at times 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. Named after the city of St Albans in Hertfordshire, England.
Triumph orbits the brown dwarf Heinlein, itself ninth body orbiting the Red Sun. Triumph is primitive and poor world, apparently self-governed with rather unusual customs and traditions. Elder Gomman is the leader of the moon’s settlers or, more likely, one small town’s worth of them. Saffron was picked up here in the episode “Our Mrs. Reynolds”.
Whitefall is the fourth moon of Athens, the ninth planet orbiting the star Georgia. A large percentage of the world is owned by a woman named Patience. Whitefall is said to not be civilization “in the strictest sense.” According to the RPG, a Blue Sun facility is rumored to be underneath one of the mountains.
