Gliese 832, also known as HD 204961 or LHS 3685, is a M1.5 dwarf located in the constellation Grus, about 16 light-years from Earth. It has about half the mass and radius of the Sun.
This star is already known to harbor Gliese 832b, a cold Jupiter-like planet discovered in 2009.
With an outer giant planet and an interior potentially rocky planet, this planetary system can be thought of as a miniature version of our Solar System, said Prof Chris Tinney, an astronomer with the University of New South Wales and a co-author of the discovery paper accepted for publication in the Astrophysical Journal (arXiv.org pre-print).

(101,294 posts)Surface gravity would go up with the cube root of mass, if the average density of a planet is the same - which would be 1.75 time Earth's in this case.
