        Description HD 164922 b is a Saturn-mass planet orbiting a late G-type star. HD 164922 c is a temperate Neptune planet discovered in a system already known to host an outer Saturn-mass planet. This planet was discovered by Benatti et al. 2020. This was a ground based discovery. The parameters listed here are those reported by Benatti et al. 2020 and were imported into the Open Exoplanet Catalogue from the NASA Exoplanet Archive.

        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.
