KOI-5 is a triple star system composed of three stars: KOI-5 A, KOI-5 B and KOI-5 C, orbiting 1,870 light-years away.
The two dim stellar companions to KOI-5A were discovered in 2016. KOI-5 A and B orbit each other every 29 years, and KOI-5 C orbits stars A and B every 400 years. KOI-5C is physically associated with the core stellar pair with probability 99.98%.
