Vulcan is a planet in the 40 Eridani system and homeworld of the Vulcans, a founding member of the United Federation of Planets.

Astronomical dataEdit


Vulcan, the second planet of the 40 Eridani system, was located 16 light years from Earth.

In 2273, at about warp factor 6, this was 2.5 Earth days travel from the Sol system. (Star Trek: The Motion Picture)



The Vulcan homeworld has no moons. (TOS: "The Man Trap") However, it does appear to have at least one close planetary companion. (Star Trek: The Motion Picture)

Vulcan's relationship to its sister planet T'Khut differs in different continuities. In some, T'Khut and Vulcan are in the same orbital pathway around their primary. In Star Trek Star Charts, they revolve around a common gravitational center that orbits around 40 Eridani, similar to the dynamic between Pluto and Charon in the Sol system.
It has not been established, in pro- or fan-fiction, if the Delta Vega seen in Star Trek also existed, and by that nomenclature, in the Primeverse.

Further informationEdit


Vulcan's climate is generally harsh, with much of the surface consisting of large deserts or mountain ranges. Furthermore, it has a considerably higher gravity and thinner atmosphere than Earth. Desert areas are prone to large amounts of heat, light and sand fire storms.

Vulcan has several tourist attractions, including active volcanoes, ancient ruins, and lava fields.

Vulcan, location of the first battle of the Mirror War (Star Trek: Mirror Wars).

During the Mirror War it was discovered a cloaked fleet of Terran Empire warships were heading towards the planet Vulcan. The USS Majestic plus all available ships headed to protect Vulcan. (Star Trek: Mirror Wars: "Approaching Dawn")

It was learned that Vulcan was home to a secret base which was The Emperor's main target in invading Vulcan. The base was supposed to be infiltrated by the Imperial Guard, under the command of Commander Blake Terval, but they failed. It is unknown what exactly the base hid, but it was deemed important.

The Starfleet force that first engaged the mirror universe's fleet came to Vulcan after they finished the battle, and helped end the attack on Vulcan. (Star Trek: Mirror Wars: "Seeing in the Dark")
