19 Oct 2010: Simpson et al. (2010) infer the orbital inclination from the parent star rotation, deriving a planet mass 0.2+0.2-0MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
24 Aug. 2006: A brown dwarf companion (M = 20 to 60 MJup, projected separation 480 AU) has been detected by direct imaging (Luhman et al. 2006, Mugrauer et al 2006). The brown dwarf is added in the base as HD 3651 B.

Sibthorpe et al. 2018 : A debris disk is detected in Herschel data.
