        Description The HARPS team announced the discovery of a planetary system around the star Gliese 163 at this year's IAU conference. The outer planet lies within the habitable zone.edit The HARPS team announced the discovery of a planetary system around the star Gliese 163 at this year's IAU conference. Gliese 163 c lies within the habitable zone for a wide range of albedo values and has an equilibrium temperature of 60C (140F).edit The HARPS team announced the discovery of the third planet arounf the M dwarf GJ 163 in a paper posted on June 4th 2013. The systems contains further periodic signals which could me caused by additional planets. However, more data is required to confirm the planetary nature of the signal.edit

        Planet sizes

        The following plot shows the approximate sizes of the planets in this system The Solar System planets are shown as a comparison. Note that unless the radius has been determined through a transit observation, this is only an approximation (see Lissauer et al. 2011b).

        Habitable zone

        The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). This is only an estimate, using the star's spectral type and mass. Note that if no green band is shown in the plot, then the planet's orbit is far outside the habitable zone. The equations of Selsis, Kasting et al are used to draw the inner and outer boundaries.
