It take away a small imagination to wish part favorite fictional universes into existence. But, because that legions of "Star Trek" fans, lock don’t need to wish: one star mechanism really exist in our Milky means galaxy. In Star Trek lore, Vulcan is the house of logic, learning and also the deep beloved an initial officer Mr. Spock. When Vulcan is fictional, the star system it belongs to–40 Eridani–is very real. It’s situated only 16.5 light-years away from Earth and its primary star can be spotted through the nude eye. So just how much is scientific research fiction and also how lot is scientific research fact?

“Could over there be one Earth-like world in this system? We have actually no method of knowing that now,” claimed Karl Stapelfeldt, cook scientist of’s Exoplanet exploration Program. Therefore while Vulcan (as much as us know) doesn’t exist, a fascinating triple sunset would take place on any type of rocky planet in the system, because 40 Eridani has actually three stars the circle every other.

The most substantial is 40 Eridani A, a dwarf star that is the mythical Vulcan’s sun. The other two room a pair, orbiting each various other at a street from 40 Eridani A. This binary pair contains a red dwarf (40 Eridani C)­ and a white dwarf star (40 Eridani B). From the surface ar of Vulcan, “they would certainly gleam brilliantly in the Vulcan sky,” follow to Rodenberry in his 1991 letter to skies & Telescope magazine.

The eco-friendly area bordering 40 Eridani A depicts the habitable zone the the star, the area wherein temperatures would be ideal for liquid water, an important ingredient because that life (Vulcan or otherwise). The habitable zone that Vulcan is closer come its dwarf star than the Earth's is come the sun because 40 Eridani A is cooler and dimmer than Sun.

If you believe in science fiction, Mr. Spock’s dreamt-up human being lives in the habitable zone the the largest star, 40 Eridani A. The habitable zone, presented as the area in blue-green, is the street from a star wherein liquid water is said to exist. Too much away from its sun and Vulcan would certainly freeze like Pluto; also close and it would certainly sizzle favor Mercury. Vulcan is perched ~ above the inside edge, loan the people its imagine desert-like top quality (at least, in a timeline where the earth remains undestroyed).

But if there to be a earth like Vulcan in the 40 Eridani system, would we have the ability to see it? not yet. “We don’t yet have a method to detect it, however is working on the modern technology to make it possible,” Stapelfeldt said.
