The Orville Wiki

Many planets in the Milky Way galaxy are known to the Planetary Union in the early 25th century. As of 2420, the Planetary Union contained over 300 member planets (and probably many more colonies and outposts). However, that number barely charted a fraction of the billions of planets that lied within the galaxy.

Minor Planets

Alibar Launch Day, Pt. 1

Launch Day, Pt. 2

Alibar being invaded by the Krill

An Earth-like planet in the Alibar system that was very close to the Krill homeworld. Because of this, the Krill tried to invade and destroy it until they crossed roads with the USS Orville.
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 the 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 vacation planet with rides, entertainment, and hotels that floated in the sky. In early 2420, Commander Kelly Grayson said 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 reported to the USS Orville that they never arrived.

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 was home to the Envall.
Epsilon 5 Nothing Left on Earth Excepting Fishes (mentioned only)

Alara confused this planet with Jintann 9.
Jintann 9 Home (mentioned only)
Solana Kitan worked 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 sat near Krill space, which made it vulnerable to attack. Kastra 4 was a new colony revolving around mining resources (probably dysonium), led by the Mining Chief Harry Leidecker. Families lived on the planet. The colony hosted weak planetary defenses that were 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 attacked Kastra 4 to scour its resources and kill the colonists, launching the Battle of Kastra 4. Kastra sent a distress call, which was answered by the Orville. The Orville destroyed the Kakov after a tense battle, and saved Kastra 4. Leidecker reported that the colony survives but dozens were seriously injured by the Kakov with at least 19 already dead. Doctor Finn led 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)
While pretending to be a member of the Vega Mining Consortium, Pria Lavesque claimed 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 was a Union farming colony near the border of Union and Krill space. By the early 25th century, Rana 3 hosted a population of over 100,000 people. However, its size and lack of military defenses made it a target of the Krill.

In the winter of 2419, the Yakar targeted 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 undermined their plans just as the Yakar entered Rana 3's orbit. Realizing that the Krill were extremely sensitive to ultraviolet radiation, Mercer and Malloy manipulated 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 launched the weapon at Rana 3, Gordon destroyed it mid-flight with the ship's torpedoes.

Retepsia Sanctuary (mentioned only)Artifacts, Pt. 1 (mentioned only)
Home of the Retepsian species. 3.4 million years ago, Retepsia was inside the territory of the Zankon empire. In those days, Retepsia was close enough to the Cruxis system that all four of its stars were individually identifiable in the night sky. The ancient inhabitants called the constellation "The Four Brothers." On or around 2421, an epic poem referring to the constellation was discovered on Retepsia. By 2421, Retepsia and Cruxis were much further apart, such that Cruxis' four stars were no longer distinguishable on Retepsia.
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.

Tarazed 3.png

Behind Cassius on the right is a picture of Tarazed 3.

Tarazed 3 was famous for both war and peace. Years ago, a battle between an unnamed space-faring civilizations led to the famous Battle of Tarazed. In early 2421, Planetary Union and Krill ambassadors signed the historic Lak'vai Pact of Tarazed 3 while in orbit over the planet.
Unnamed planet of the Resistance The Road Not Taken
Resistance planet.png
Home to a secret Resistance base led by Alara Kitan. The planet seemed lush from space. The base was located in a forested mountain area.
Unuk 4 Pria

Unuk 4

Unuk 4 was known for its remarkable beauty. The surface boasted rolling hills as well as vast, fertile valleys cut by long, blue-grey rivers. Visiting the world was strictly forbidden by the Union due to its violent inhabitants who sacrificed anyone they could capture to a "raccoon god" by methodically dismembering them.

Vendek 2 Tomorrow, and Tomorrow, and Tomorrow

Two Kaylon Spheres approaching Vendek 2

A gas giant planet with a covariant ring system which was used by the Orville to elude a pair of Kaylon spheres. It is located in the Vendek system.


The following were unidentified planets:

  • The time-traveling thief Pria Lavesque said there is a planet on the frontier where business negotiations began by showing their genitals.[3]
  • An unnamed gas giant planet was orbited by 32 moons, including a habitable moon landed upon by Claire, her children, and Isaac.[4]
  • The Chog were moved to an undisclosed planet between the years 2420 and 2423 while their homeworld was terraformed.[5]

Additionally John LaMarr of an alternate timeline said that an asteroid field next to a black hole "used to be a planet" before the black hole tore it apart.[6]
