Observability Predictor 
Remarks
Pecaut et al. (2012) have revised the age of Upper Scorpius to 11 Myr from the 5 Myr previously estimated. As a consequence, the estimation of the planet mass has increased to 14 Mjup from the previous estimates of 8 Mjup, putting this planet in the brown dwarf range.(Lafrenière et al. 2010): companions more massive than 1 Mjup, 2 Mjup and 4 Mjup are ruled out for separations ≳ 440 AU, 100 AU and 50 AU respectively.
(Lafrenière et al. 2008): spectral type L4+1-2
