Groombridge 34 is a binary star system in the northern constellation of Andromeda. Based upon parallax measurements taken by the Hipparcos spacecraft, the system is located about 11.7 light-years from Sol, which positions the pair among the nearest stars to the solar system.[1]

Background[]

Both stars in the system are small, dim red dwarf stars. They orbit around their common barycenter in a nearly circular orbit with a separation of about 147 AU and a period of around 2,600 years. Both stars exhibit random variation in luminosity due to flares and they have been given variable star designations: the brighter member Groombridge 34 A is designated GX And, while the smaller component Groombridge 34 B is designated GQ And.

Groombrdge 34 A has a planet orbiting it.

  • Forward Fire Base Langston - located on the planet orbiting Groombridge 34 A, the Fire Base is subject to constant harassment attacks and sniper fire from the Chigs.[3]

Battles in Groombridge 34[]
