This is a part of abinary star system consisting of two components separated by 24″.[8] The primary component, GJ 3685 (also known as GJ 3685 A), is a very oldred dwarf that is also aflare star. A 20-minute flare was observed in 2004 by theGALEX satellite.[9] Its companion, GJ 3686, is another faint red dwarf with aspectral type of M5. It is also known as LP 613-50 and is also located roughly the same distance as its primary.[10]
