Groombridge 34 is a binary star system located about 11.7 light-years from the Sun. It consists of two red dwarfs in a nearly circular orbit with a separation of about 147 AU. Both stars in this pair exhibit variability due to random flares and they have been given variable star designations. (The brighter member Groombridge 34 A is designated GX And, and the other member is designated GQ And).
