Planetary system 

In September 2012, astronomers using the HARPS instrument announced the discovery of two planets orbiting Gliese 163. One planet, Gliese 163 c, with an orbital period of 26 days, and a minimum mass of 7.2 Earth masses, was considered potentially in the habitable zone, although hotter than Earth. A second planet, Gliese 163 b, was also announced, with a period of 1 day. It would be too hot to be considered habitable. Evidence was also found for a third planet orbiting further out than c and b. In June 2013, it was concluded that at least 3 planets orbit around the star with fourth planet being a possibility.
