A faint stellar companion lies 1364 AUs away. Mugrauer et al. (2022) regard it as a white dwarf, although Michel & Mugrauer (2024) report physical parameters seemingly more compatible with a cool low-mass M dwarf star (m_B = 0.15 M_Sol, T = 3133 K) rather than a white dwarf, unless this is actually an ultracool degenerate object.
