      Description The star HAT-P-7 is located in the constellation Cygnus and in the field of view of the Kepler spacecraft. Measurements of the Rossiter-McLaughlin effect combined with determination of the stellar equator suggest an inclination of 120 degrees to the stellar equator. Retrograde orbits are difficult to explain with standard disk migration. Planet-planet scattering or the Kozei effect are able to produce retrograde orbits.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.
