ROXs42Bb是一个亚恒星天体，并且可能是光谱M型联星成员星ROXs42B的行星质量天体，还可能位于蛇夫座ρ星云复合体内。 ROXs42Bb是由多伦多大学的天文学家塞恩·柯里（ThayneCurrie）等人发现于2013年。

2014年1月9日 · An unusual stellar object named ROXs 42Bb may represent a new kind of planets or it may be a very rare planet-mass brown dwarf, according to a group of astronomers from Canada, Germany, Japan and the United States.

Detailed information about planet ROXs 42B (AB)b and its parameters. (Currie et al., ApJ, 707, 104, 2014): spectral type L0±1. Very dusty/cloudy planet. (Bowler et al. 2014): strong FeH absorptions. (Bowler et al. 2014): a candidate for a second companion marked in previous observations is very likely a background object.
