28 Sep 2011: This object has a M sin i = 14.3 MJup (Bouchy et al. 2009). But a direct image shows that the orbit is viewed almost face-on, leading to a mass 280 MJup (Evans et al. 2011).
Kiefer et al. 2021 : qualified as stellar object by Gaia astrometry.
15 Jan 2026: Planetary mass is confirmed by Piccinini et al. (2026) refuting previous claims of a stellar nature.
