GJ 3522 (G 41-14) is a nearby triple star system, consisting out of a short-period double-line spectroscopic binary[1] and an outer companion that was discovered with adaptive optics on the CFHT.[2] The system is 22 light-years (6.8 parsec) from Earth.[3]

The inner binary orbit each other every 7.6 days. Orbiting around the inner binary the outer companion completes an orbit every 5.7 years.[4] The system has a spectral type of M3.5.[2]

The star shows flares in the optical and x-ray. It also shows activity in H-alpha and ultraviolet.[5]
