Vulcan (also known as Vulcan/Vulcanis A II, Nevasa II or 40 Eridani A II) was a planet, the second planet in the 40 Eridani star system, in orbit of the star 40 Eridani A. A class M desert planet, Vulcan was inhabited by the Vulcan civilization, who refered to their world as T'Khasi or Ti-Valka'ain. As the Vulcan homeworld Vulcan was the capital planet of the Confederacy of Vulcan, and later a founding world in both the Coalition of Planets and United Federation of Planets.

Vulcan orbited 40 Eridani A, known as Nevasa to the Vulcans, the primary orange K class star in the trinary Vulcan system. The other two stars in the system, 40 Eridani B and C, blue and red dwarfs respectively, co-orbited the A star at some distance and were not immediately visible in the Vulcan sky. (ST references: The Worlds of the Federation, Star Charts; TOS - Vulcan's Soul novel: Exodus; ST roleplay module: Aliens)
Vulcan's orbital period (year) was 203 days long. [citation needed]
Vulcan had no moon, but did have a number of nearby planets, most notably T'Khut, with which it shared an orbit around a common center of gravity; the two worlds were a mere 149,895.3579 kilometers apart, and T'Khut would fill the sky of the single hemisphere of Vulcan it was visible from due to the planets being tidally locked. (TOS episode: "The Man Trap"; ST reference: The Worlds of the Federation; TOS novel: Sarek)
T'Khut itself did have a moon, called T'Rukhemai, home of the Vulcanis Lunar Colony. (TOS novel: Sarek; VOY episode: "Unimatrix Zero"; VOY novel: Pathways)
Also passing near enough in its orbit that Vulcan could be clearly seen in the sky was the icy planet Delta Vega. (TOS movie: Star Trek; TOS comic: "Nero, Number Four")
Vulcan was a harsh, desert planet with barely a quarter of its surface area containing water. It possessed a thin atmosphere and high gravity (1.4 G). (ST reference: Aliens)
Vulcan had three primary continents called Na'nam, Han-shir and Xir'tan. The first were enormous land masses that were divided into various provinces whilst the third was an island somewhat larger than the Earth continent of Australia. (LUG roleplay module: The Way of Kolinahr: The Vulcans)
Due to the strong tidal forces brought about by the planet's interaction with T'Khut Vulcan was highly volcanically active. This generated a number of impressive lava spectacles, such as the Fire Plains. (ST - New Worlds, New Civilizations short story: "Tempered by the Forge"; ENT episode: "Home")
Vulcan's geology and desert environment produced starkly up-thrust craggy and inhospitable mountains, with jagged and steep formations cut out by wind swept sand. (ST roleplay modules: Aliens, Worlds)
Vulcan maintained the oxygen in its atmosphere by deriving phytoplankton from its oceans, which existed as microscopic organisms that make up 90% of all planetary oxygenation processes, including those of Earth. Despite being a desert planet and not having a suitable source of oxygen in viable plant-life throughout most of their year, there is a sufficient amount of oxygenation occurring within the environment from the microbic water. [citation needed]
Though a dry desert occupied 96% of the planet's surface by the 23rd century, fossil records indicated that early Vulcan possessed 90% water along with a few islands with nothing but a hot sea present on the planet. Thousands of years later, when the proto-Vulcans developed and began to form tribes, 40 Eridani A erupt a massive solar flare that scorched the planet's surface; resulting in many native creatures dying, those which survived taking shelter in caves or other safe places on the opposite end of the planet. (TOS novel: Spock's World)
Early in the Dominion War, Benjamin Sisko expressed his concerns to Admiral Zach Warner that the Dominion would eventually be able to invade Vulcan if Starfleet kept up its defense posture. The routes between Vulcan and Earth and Alpha Centauri were critical to the Federation. (DS9 novelizations: Call to Arms..., ...Sacrifice of Angels)
The concerns for Vulcan lasted throughout the year, with fighting near the Vulcan border. Later, the fall of Betazed made the possibility of an invasion of Vulcan very likely. (DS9 episodes: "Favor the Bold", "In the Pale Moonlight", "The Reckoning")
During the Borg Invasion of 2381, several Borg cubes moved to attack Vulcan. They managed to begin an orbital bombardment which inflicted severe damage to notable locations on the planet, including the Vulcan's Forge. However, the planet was saved from destruction when former Earth Captain Erika Hernandez managed to influence the collective to attack itself, severely damaging the cubes attacking Vulcan, which were later destroyed by a Starfleet task force including the USS Atlas and USS Prometheus. (ST - Destiny novel: Lost Souls)
In the alternate timeline created by Nero's temporal incursion, Vulcan was destroyed in the year 2258. The planet was obliterated by an artificial singularity created when Nero launched a red matter device into the planet's core. Of a population of 6 billion, approximately ten thousand escaped the devastation, and though their cultural legacy would survive, the Vulcan people became an endangered species. (TOS movie & novelization: Star Trek)
Typically, there were no lost civilizations on the planet as new cities were always integrated into the older ones which meant that ruins remained. In addition, the planet's manufacturing and heavy industry had, for centuries, been conducted in the asteroid belt within the system. The only industry that was allowed on the surface were those that neither despoiled the environment nor disturbed its tranquillity such as music crafting. (TOS novel: Dwellers in the Crucible)
The Vulcan population was approximatly 4.9 billion in the year 2378. (ST reference: Star Charts)
The heat of Vulcan summer often killed off post vegetation, with plant life only flourishing once rains came. During the hotter periods on Vulcan, only carnivorous plants out in the desert that were still survived in times of drought by catching any animal that was weakened by thirst. (TOS novel: The Vulcan Academy Murders)

40 Eridani system. Vulcan is located 16 light years from Earth.
The Vulcan homeworld has no moons. However, it does appear to have close planetary companions.
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 volcanos, ancient ruins, and lava fields.
In 2374, when Betazed fell during the Dominion War, it was noted that the Dominion would be in a position to threaten Vulcan. Shortly thereafter, it was confirmed that the Dominion had been building up its forces on Betazed and that they would be able to launch an attack on Vulcan. (DS9: "In the Pale Moonlight", "The Reckoning")
During the Dominion War the Dominion launched three unsuccessful attempts to conquer Vulcan. (The Dominion War Sourcebook: The Fires of Armageddon)
In an alternate timeline Vulcan was destroyed by the Romulan Nero in 2258. (Star Trek)
As early as the late 21st century or early 22nd century, Vulcan had contact with the Cardassians, Klingons, Tholians, Tellarites, Trill, and humans, among others.
Before co-founding the Federation in 2161, Vulcan was in conflict with Andoria. It controlled the Coridan government, and had exchanged ambassadors with Earth and Qo'noS, among others.
During the mid-22nd century, the death penalty was still common practice in Vulcan courts for a small number of offences, including treason.
The Suliban launched a massive assault on both Earth and Vulcan. The Suliban who attacked Vulcan destroyed the 40 Eridani-A Spacedock, but no starships were docked at the time. The Enterprise-A diverted course to assist the USS Bozeman in relief efforts. (Harry Potter and the Return of James T. Kirk: "Relief Mission")
During "The Mirror Shattered", Part 3 of the Star Trek: Mirror Wars pilot episode, it was discovered that what Starfleet thought was the main mirror universe invasion fleet was actually a diversion fleet, while a cloaked fleet of warships headed 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")
Sometime after returning from New Bolarus and Milami Thall's entry into Starfleet Academy, Ualla Thall and the Federation starship she was serving aboard went to Vulcan to treat an outbreak of Rigelian fever. Milami Thall took the time to visit the T'Peral Plateau.
Lieutenant T'Piam was born and raised on Vulcan. (Star Trek: The Cantabrian Expeditions)
