If ASR28b is confirmed as member of NGC 1333 Cluster, spectral type L4 is implied and a corresponding mass of 5 M_Jup with an approximate mass ratio of 0.15 (assuming a 0.033 M_Sol primary). If on the other hand the mass of primary component ASR28 is confirmed to be much less than 0.033 M_Sol (~0.003-0.004 M_Sol according to Scholz et al. 2012), for a mass ratio of 0.15 corresponding mass of the secondary component is about 0.5 M_Jup.
