Many planets in the Milky Way galaxy are known to the Planetary Union in the early 25th century. As of 2420, the Planetary Union contains over 300 planets. However, it has still barely charted a fraction of the billions of planets that lie within the galaxy.
| Name | Episode Appearance |
|---|---|
| Alamak 3 | A Happy Refrain (mentioned only) |
| In late 2420, Doctor Claire Finn delivers to Captain Ed Mercer an update on the vaccine shipment to Alamak 3.
Alamak is an actual star most commonly known as Gamma Andromedae, about 350 light years from Earth. | |
| Antares 2 | Deflectors (mentioned only) |
| Cassius taught a biohistory class on Antares 2 which included the children of Groogen, a Katrudian.
In the real world, Antares, also designated Alpha Scorpii, is brightest object in the constellation of Scorpius. It is located roughly 600 light years from Earth, a distance which the Orville's quantum drive can cross in 60 hours, 2 and a half days. | |
| Arboreus Prime | Into the Fold
(mentioned only) |
| Renowned as a vacation planet with rides, entertainment, and hotels that float in the sky. In early 2420, Commander Kelly Grayson says that it was raining all over the planet. Doctor Claire Finn, her sons Ty and Marcus, and Isaac meant to visit the planet for a holiday but their shuttle was sucked into the gravity well of a Class-2 spatial fold. A dockmaster on the planet reports to the USS Orville that they never arrived. | |
| Calivon | Command Performance The Road Not Taken (mentioned only) |
 The home world of the Calivon. Host of the highly advanced Calivon species and their Calivon Zoo. | |
| Chara 3 | Krill |
| Host of a former Union colony, destroyed in a Krill raid by the Krill destroyer Yakar for its resources. A male colonist's head was taken by the Krill and pulpified by High Priest Sazeron in a bloody religious ritual. | |
| Deneb 3 | Command Performance
(mentioned only) |
| A planet mentioned by simulations of Ed's parents, Ben and Jeannie Mercer, as their weekend getaway destination.
In the real world, Deneb, also designated Alpha Cygni, is the brightest star in the constellation of Cygnus, the swan. It is located 2,616 light years from Earth, a distance which the Orville's quantum drive can cross in 261.6 hours, just short of 11 days. | |
| Elnath 4 | About a Girl
(mentioned only) |
| Elnath 4 was saved from an asteroid by the Orville in October 2419. Were it not for the Orville's "cutting beam," the asteroid would have collided in one month, 17 days.
In the real world, Beta Tauri, officially named Elnath (sometimes called Alnath), is the second-brightest star in the constellation of Taurus. It is located 134 light years away from Earth, a distance which the Orville's quantum drive would cross in just short of 13 and a half hours. | |
| Envall homeworld | Blood of Patriots (mentioned only) |
| Located in the distant star system of Lakkar B, this planet is home to the Envall. | |
| Epsilon 5 | Nothing Left on Earth Excepting Fishes
(mentioned only) |
| A planet in the Epsilon system. The Orville makes multiple supply runs to the planet in 2420. | |
| Jintann 8 | Home (mentioned only) |
| Alara gets this planet confused with Jintann 9. | |
| Jintann 9 | Home (mentioned only) |
| Solana Kitan works at a laboratory on Jintann 9, which was "set up" by September 2420. | |
| Kastra 4 | Krill Nothing Left on Earth Excepting Fishes (mentioned only) |
 The Orville and the Kakov in orbit over Kastra 4. A colony of 100,000 individuals and a member planet of the Planetary Union.[1] It sits near Krill space, which makes it vulnerable to attack. Kastra 4 is a new colony revolving around mining resources (probably dysonium), led by the Mining Chief Harry Leidecker. Families live on the planet. The colony hosts weak planetary defenses that are insufficient to fend off enemy attacks; and at the time of December 2419, it had been attacked three times in the past month.[2] In December, the Krill destroyer Kakov attacks Kastra 4 to scour its resources and kill the colonists launching the Battle of Kastra 4. Kastra sends a distress call, which is answered by the Orville. The Orville destroys the Kakov after a tense battle, and saves Kastra 4. Leidecker reports that the colony survives but dozens were seriously injured by the Kakov with at least 19 already dead. Doctor Finn leads a medical away team to the colony.[2] | |
| Mizar 2 | The Word of Avis, Pt. 1 |
| A planet home to a primitive culture. Union xenoanthropologists Darden, Karx, Franz and Celeste were assigned to study this culture. | |
| Pollux 5 | Pria (mentioned only) |
| In her act as a member of the Vega Mining Consortium, Pria Lavesque claims to have encountered a dark matter storm on a mining expedition to Pollux 5.
In the real world, Pollux, also designated Beta Geminorum, is the brightest star northern constellation of Gemini. The closest giant star to the Sun, it is located approximately 34 light years from Earth, a distance which the Orville's quantum drive can cross in just short of 3 and a half hours. | |
| Rana 3 | Krill
Blood of Patriots (mentioned only) |
 The farming colony of Rana 3 as seen from space. Rana 3 is a Union farming colony near the border between Union and Krill space. By the early 25th century, Rana 3 hosts a population of over 100,000 people. However, its size and lack of military defenses make it a target of the Krill. In the winter of 2419, the Yakar targets Rana 3 for an attack using a prototype weapon: the neutron field generator, theoretically capable of destroying all life on a continent within a matter of minutes. Undercover Union officers Ed Mercer and Gordon Malloy successfully undermine their plans just as the Yakar enters Rana 3's orbit. Realizing that the Krill are extremely sensitive to ultraviolet radiation, Mercer and Malloy manipulate the ship's lights to produce a lethal level of brightness, wiping out the vast majority of the crew and saving Rana 3. Though the Yakar's automatic controls launch the weapon at Rana 3, Gordon successfully destroys it mid-flight with the ship's torpedoes. | |
| Retepsia | Sanctuary (mentioned only) |
| Home of the Retepsian species. | |
| Rhealon 4 | Tomorrow, and Tomorrow, and Tomorrow (mentioned only) |
| While a Union Point cadet, Kelly Grayson was aboard a ship breaking gravity on Rhealon 4. | |

  Behind Cassius on the right is a picture of Tarazed 3. | |
| Unuk 4 | Pria |
  Unuk 4 Unuk 4 is known for its remarkable beauty. The surface boasts rolling hills as well as vast, fertile valleys cut by long, blue-grey rivers. Visiting the world is strictly forbidden by Union due to its violent inhabitants who sacrifice anyone they can capture to a "raccoon god" by methodically dismembering them. | |
| Vendek 2 | Tomorrow, and Tomorrow, and Tomorrow |
| A planet with a covariant ring system which was used by the Orville to elude a pair of Kaylon spheres. | |

The following are unidentified planets:
- The time-traveling thief Pria Lavesque says there is a planet on the frontier where business negotiations begin by showing their genitals.[3]
- An unnamed gas giant is orbited by 32 moons, including a habitable moon landed upon by Claire, her children, and Isaac.[4]
- The Chog are moved this undisclosed planet between the years 2420 and 2423 while their homeworld is terraformed.[5]
Additionally John LaMarr of an alternate timeline says that an asteroid field next to a black hole "used to be a planet," before the black hole tore it apart.[6]
