      Description The star Gliese 849 is a red dwarf in the constellation of Aquarius. Gliese 849 b is the inner of the system's two known planets.edit The radial velocity date for Gliese 849 has poor phase coverage for the orbit of Gliese 849 c, however its parameters can be better constrained by considering the dynamical stability of the two-planet system.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.
