      Description Kepler-424 b is a Hot Jupiter in a two-planet system. It was discovered using the Keple Space Telescope. The mass was determined using radial velocity measurements from the Hobby-Eberly Telescope and its High Resolution Spectrograph (HRS).edit Kepler-424 c has been discovered with the Hobby-Eberly Telescope and its High Resolution Spectrograph (HRS). Kepler-424 is a two planet system. This is unusual as the inner planet is a Hot Jupiter which come preferentially in single planet systems.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.
