Sol or the Sun was the home star of the Sol System, a planetary system about twenty-seven thousand light years from the galactic centre of Mutter's Spiral.



Historical overview

  • At an early stage of development, Venus supported native sentient life. (MA: Venusian Lullaby)
An asteroid belt somehow resulted from the time looping of the fifth planet. Perhaps the Time Lords themselves imported the asteroids as replacement for the excess mass missing when they removed the Fifth Planet.
  • In the mid-20th century, humans on Earth began exploring their solar system via probes and, tentatively at first, with manned missions. Earth's moon was the first object in the Sol system to be visited by humans -- at least, according to the official historical record (DW: Blink, et al). Later, missions to Mars (DW: The Ambassadors of Death) and other planets occurred. For much of the century, the general public believed there to have been nine planets, although a change in the official definition of "planet" disqualified one of them, Pluto, to much controversy in the early 21st century (contemporary accounts); at some later date, Pluto's planetary status was restored (implied DW: The Sun Makers).
  • Circa 2009 CE, Earth was forceably relocated to the Medusa Cascade by the Daleks. The relocation of Earth seemed to have no lasting effects on the Sol system; even Earth's Moon remained in place until the Doctor returned Earth to its proper position. (DW: The Stolen Earth/Journey's End). The end result of the incident was that the general populace of Earth were now aware of the existence of alien life (TW: Children of Earth: Day One, et al), ushering in the planet's increased presence in interstellar affairs from the 21st century onward (DW: The Christmas Invasion, TW: Everything Changes, et al)
  • Around 2089, the Grandaughter of Captain Adelaide Brook decided to pilot the first ever lightspeed earth ship to Proxima Centuri, inspired by her Grandmother who blew up a base on Mars to save the human race. Soon after that, the human race started colonising other Star Systems.
In some unknown way, the move once more devastated Earth, which less informed people attributed to solar flares.

Comings and goings

We do not know whether or not this planetoid originated from outside the Sol system.
  • Originally orbiting Sol at the same distance as Earth, Mondas left orbit and wandered out further into the Sol system. (DW: The Tenth Planet)
  • As noted above, the Earth has been relocated at least twice in its history, only to be either shortly or eventually returned to its original location (DW: The Mysterious Planet and The Stolen Earth).

(18 votes)

The Sol System, otherwise referred to by UNSC personnel and Humans alike as the Solar System, is the home star system for Humans. The system's G-class star is named Sol, hence the system's name.


Major Planets and Moons

  • Mercury
  • Venus
  • Earth - The Human/UNSC Headquarters (HQ)/Homeworld.
  • Mars - A major site of the Interplanetary War and later during the Human-Covenant War it was the site of the Battle of Mare Erythraeum. Has been terraformed to have an Earth-like climate.
  • Jupiter - A gas giant, Jupiter is the largest planet in the Sol System.
    • Io - The site of a UNSC listening post. On October 20, 2552, the listening post on Io detects 15 Covenant ships inbound under the command of the Prophet of Regret.[1]
    • Europa - It contains a UNSC base and a substantial colony. Spartans Linda and Will were once assigned to a mission on this satellite.
    • Callisto - The Second Largest Jovian Moon. The site of the signing of the Callisto Treaty and a number of UNSC bases.
    • Ganymede - The EVA Armor was developed here, home to a number of colonists.
  • Saturn - A gas giant known for its clearly visible surrounding rings, unlike the other gas giants whose rings are rather dim. Saturn is the second largest planet in the Sol System. Its practical uses to the UNSC are limited, and therefore it is mostly just a tourist destination.[2]
  • Uranus - An icy gas giant about twice as far away as Saturn from Sol. Its distance from Sol makes it of little use to the UNSC.
  • Neptune - Furthest away from Sol, it is another icy gas giant similar to Uranus.

Dwarf Planets

  • Ceres - The largest asteroid to have ever been discovered by humanity.
  • Eris - Currently the largest Dwarf Planet known. It is almost 10% larger than Pluto in diameter.
  • Pluto - In the 1930's, Pluto was discovered and named a planet. Many years later in 2006, scientists debated over if it was really big enough to actually be considered a planet, and after much talk, it was declassified. The Pluto Slipstream Monitoring Station Democritus is stationed in orbit around it. On November 3, 2552, the Monitoring Station detected Cortana's signal in Slipspace with Dr. Halsey's message to Lord Hood. Pluto has three moons: Nix, Hydra, and Charon.
  • Haumea - The most notable feature is its highly eliptical shape.
  • Makemake - The second most distant dwarf planet, its lack of moons mean it and Ceres are the only two known dwarf planets orbiting Sol without moons.


  • Sol is the original Latin and the actual scientific name for Earth's Sun. This designation and name has actually been used instead of "Solar System" in many Sci-fi novels.

The Star Trek Expanded Universe Database is for fanon and related content. See for the canon Star Trek wiki.

The Sol system (or Solar system or Terran system) is a single-star system located in Sector 001 of the Alpha Quadrant. It contains eight planets, one of which is natively inhabited.

The Sol system is also the main base of operations for the Federation and Starfleet, with most of their facilities spread between the third and fourth planets.

From Teletraan I: The Transformers Wiki

To get to "another galaxy", you've got to go past a few hundred billion of these.

A solar system (more properly, star system or stellar system) is a grouping of one or more stars, commonly orbited by one or more planets and various other cosmic detritus.

Transformers typically travel to different star systems in the course of their adventures. As star systems are generally several light years apart, this requires some sort of faster-than-light propulsion, or an instantaneous gateway system of some kind, such as a space bridge.



Notable solar systems in Transformers fiction include:

Marvel Comics

  • The Alpha Centauri system, home to the planet Cybertron.
  • An unnamed system where the Matrix Quest took place, home to the following planets:
    • Cheyne
    • Pz-Zazz
    • Pequod
    • Cameron, and its barren moon VsQs

IDW Comics

  • The Lambda Scorpii system, also home to the planet Cybertron.
  • The Kol system, home to the planet Varas Centralus.
  • The Eigerson-48 system, home to the planet Mumu-Obscura.

Those poor, confused writers

A star system should not be confused with a galaxy, which is a massive grouping of millions of star systems. A single galaxy is unfathomably huge, with our own Milky Way Galaxy containing several hundred billion stars. The distances between galaxies are several orders of magnitude greater than the distances between the star systems they contain.

Unfortunately, in Transformers fiction, "galaxy" is frequently used in places where "star system" makes a lot more sense, or at least is not as jarring. Given that all interstellar travel is based on fictional technologies, it's not inconceivable that characters might actually come from or travel to other galaxies. But the notion seems an unnecessary complication at best (a single galaxy is a more-than-ample playground for fictional adventures) and often outright contradicts information given elsewhere. Cartoon animation, for example, almost never supports the idea that characters actually leave the Milky Way galaxy.

Notable examples of galaxy/solar system confusion include:

Remarkably, the Generation One cartoon seems to portray Cybertron consistently as being originally located outside our galaxy. The episode "Roll For It" shows Cybertron outside of a spiral galaxy (though it is also shown against a field of stars, instead of the empty black void that should be there if it's located in inter-galactic space). The episode later shows a rather confusing visual of the space bridge energy beam emanating from an empty point in space alongside a galaxy, but not going into the galaxy. Later, in "The Ultimate Doom", Optimus Prime comments that the pylons of the Decepticons' Cybertron-centered space bridge "form a pyramid, with the apex beyond this galaxy."
