Furlan et al. (2017) regard it as primary component of a widely separated binary, triple or even quadruple system including a trio of faint M dwarfs 0,651, 0.914 and 1.9 arcseconds away (143, 201 and 418 AUs at 220 pc). Evans et al. (2024) confirm association for the inner pair, to be ascertained for the outer one.
