Furlan et al. (2017) reported three candidate companion stars 0.032, 2.89 and 3.08 arcseconds away (9.3, 838 and 893 AUs at 290 pc). Michel & Mugrauer (2024) confirm Kepler-908 as primary component of a triple system including two M dwarfs at larger separation (2177 and 2044 AUs). Based on estimated luminosity the innermost candidate companion is compatible with a late G to early K dwarf.
