            Description This planet candidate was discovered with the Kepler spacecraft. Its host star gets periodically fainter whenever the planet is in front of the star. Because there are multiple phenomena that can create a signal that looks similar to a planetary transit, the candidates have to be confirmed with another method. The closely packed system Kepler-33 was validated by multiplicity (Lissauer et al. 2012). However, the mass of the planets is not known yet.edit This planet candidate was discovered with the Kepler spacecraft.

            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.
