Gamma Arietis

Gamma Arietis (also known as Mesarthim) is a trinary star system in Federation space consisting of the three companion stars located about 60 parsecs (200 light years) from Earth, where it is visible in the constellation of Aries. (TOS novel: Rihannsu - "Swordhunt")

The planets Vellurius (Starbase 20), Valerian and the Mesarth species's homeworld (planet Mesarthim) are all located in this triple system. (TOS comic: "There's No Space Like Gnomes'!"; novel: Crucible - "The Fire and the Rose")


 * Since Gamma Arietis is a "real" star system, modern scientists know a few things about its distance and makeup that weren't in its Star Trek'' mentions.
