        Description This planet was discovered by the Kepler spacecraft. The planet is part of a multiplanetary system. Its planetary nature has been confirmed using transit timing variations which arise because the planets in one system pull on each other and slightly alter the transit times.edit This planet was discovered by the Kepler spacecraft. The planet is part of a multiplanetary system. Its planetary nature has been confirmed using transit timing variations which arise because the planets in one system pull on each other and slightly alter the transit times.edit This is a Kepler Object of Interest from the Q1-Q12 dataset. It has been flagged as a possible transit event but has not been confirmed to be a planet yet.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.
