Simbad=ADS+246Groombridge 34 is a binary star system that consists of two
red dwarf stars in a nearly circular orbit with a separation of about 147astronomical unit s. 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").References
