17 Feb 2011: Simulation by Chauvin et al. (2011) show that the system HD 196885A b-HD 196885 B is more stable if highly non-coplanar. 01 Nov. 07: A M1V dwarf companion at 0.7'' = 23 AU (Chauvin et al. 2007)
23 Oct. 04: Star in double system
17 Feb 2011: HD 196885 A is part of a binary system with a 0.45 MSun companion HD 196885 B at 21 AU
with an orbital inclination 116.8 ± 0.7 deg (Chauvin et al. 2011).
