GJ 3522 (G 41–14) is a nearbytriple star system, consisting out of a short-period double-linespectroscopic binary[4] and an outer companion that was discovered with adaptive optics on theCFHT.[5] The system is 22light-years (6.8parsec) 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.[6] The system has a spectral type of M3.5.[5]
The star shows flares in the optical andx-ray. It also shows activity inH-alpha andultraviolet.[7]
