(Delta Vega was not a creation of the split timeline so it exists in the prime universe. Remove references to the alternate timeline, the "Star Trek" reference will suffice.)

According to ''[[Star Trek: Communicator]]'' (issue 136, p. 27), the additional planets were removed for the reason that the scene took place during daytime, so a night sky was not appropriate, and they were elements that distracted the viewer from a scene intended to take place on a far-off monastic temple. Vulcan in and of itself was considered to be interesting enough without cluttering the sky with these planets.

''[[Star Trek: Star Charts]]'' also supports the theory that the Vulcan system is the 40 Eridani A system. The name of the star is listed as 40 Eridani A (Omicron<sup>2</sup> Eridani A). There are three planets and an asteroid belt in the system. Planet I is class-B. This classification is also used, in ''Star Trek: Star Charts'', to describe [[Mercury (planet)|Mercury]]. Planet II, Vulcan, is [[Class M|class-M]]. Planet III, T'Khut, is class-G and has a moon. In ''Star Trek: Star Charts'', class-G is a classification of planets similar to Delta Vega. Vulcan and T'Khut are twin planets. The stars 40 Eridani B and C have no planets. The distance between A and B is 400 [[astronomical unit|AU]], and between B and C is 44 AU.

AT: "xx" The Vulcan system was an inhabited star system in the Alpha Quadrant. The system consisted of a primary and several planets, including Delta Vega and Vulcan. Neighbouring the Andorian system, it was located 16 light years from the Sol system. (ENT: "The Andorian Incident", "Home"; Star Trek)

In 2293, the location of Vulcan in the Milky Way Galaxy was labeled in a star chart that was in Captain James T. Kirk's quarters aboard the USS Enterprise-A. (Star Trek VI: The Undiscovered Country, okudagram)

The Vulcan sun was so bright, as seen from the planet Vulcan, that it caused the evolution of the Vulcan inner eyelid. (ENT: "The Forge"; TOS: "Operation -- Annihilate!")

In 2258, in the alternate reality, Delta Vega was the location of a Starfleet outpost. That year, Nero destroyed the planet Vulcan, leaving a small black hole in its place. (Star Trek)

Vulcan system is a placename for the canon name of the system. Vulcans were identified as an Alpha Quadrant species in "In the Flesh".

The original theatrical edit of Star Trek: The Motion Picture depicted four large orbs in the Vulcan sky. They were removed in the DVD release of the director's edition of The Motion Picture and replaced by an orange sky. According to Star Trek: Communicator (issue 136, p. 27), the additional planets were removed for the reason that the scene took place during daytime, so a night sky was not appropriate, and they were elements that distracted the viewer from a scene intended to take place on a far-off monastic temple. Vulcan in and of itself was considered to be interesting enough without cluttering the sky with these planets.

According to Star Trek: Star Charts (pg. 58), T'Khut was the name of the Vulcans twin planet that was visible from the planets surface. T'Khut was classified as a G-class world, and had one moon. The Vulcan system also known as the 40 Eridani A System or Omicron2 Ceti System was a trinary star system. 40 Eridani A had a spectral type of K1V with an absolute magnitude of 6.0. 40 Eridani B had a spectral type of AVII with an absolute magnitude of 11.2. 40 Eridani C had a spectral type of M4V with an absolute magnitude of 12.3. The distance between A and B was 400 AU; distance between B and C was 44 AU. The orbital period of this system was 248 years.

There has been however no direct canonical reference of the Vulcan system being the 40 Eridani A system, although that is widely considered to be the case. In "Home" and "Daedalus", Vulcan was mentioned as being slightly over sixteen light years from Earth, the same distance between Earth and 40 Eridani A. According to text commentary by Michael and Denise Okuda for "The Forge" on the ENT Season 4 DVD, the possibility of Vulcan being located in the 40 Eridani system originated from a suggestion by novelist James Blish. When three astronomers (Sallie Baliunas, Robert Donahue, and George Nassiopoulas) who had been studying the system at Mount Wilson Observatory published a letter, stating that the star "40 Eridani A could support a planet with Earth-like life" and that it would "have the Sun's brightness for a planet 50 million miles away", they theorized that Vulcan could be in orbit of this star, a theory Gene Roddenberry himself supported by signing their letter, according to Sky & Telescope, 1991 July.

Recent real world discoveries have confirmed the likely presence of at least three planets in the Epsilon Eridanii system. [1]
