We report the detection of GJ 832c , a super-Earth orbiting near the inner edge of the habitable zone of GJ 832 , an M dwarf previously known to host a Jupiter analog in a nearly-circular 9.4-year orbit .
The combination of precise radial-velocity measurements from three telescopes reveals the presence of a planet with a period of 35.68 \pm 0.03 days and minimum mass ( m sin i ) of 5.4 \pm 1.0 Earth masses .
GJ 832c moves on a low-eccentricity orbit ( e = 0.18 \pm 0.13 ) towards the inner edge of the habitable zone .
However , given the large mass of the planet , it seems likely that it would possess a massive atmosphere , which may well render the planet inhospitable .
Indeed , it is perhaps more likely that GJ 832c is a “ super-Venus , ” featuring significant greenhouse forcing .
With an outer giant planet and an interior , potentially rocky planet , the GJ 832 planetary system can be thought of as a miniature version of our own Solar system .
