Furlan et al. (2017): Kepler-1802 is likely the secondary component of a multiple system composed of a slightly brighter late K dwarf companion ~377 AUs away and a possible third fainter late K to early M dwarf star further away (~1650 AUs). Separations increase if the host star's distance is assumed to be 636.9 pc: ~560 and ~2455 AUs respectively.
