          Description Kepler-37 b is a tiny planet, about the size of our Moon. Due to the high irradiation it has probably a rocky surface with no atmosphere or water, similar to Mercury. NASA has given the planetary system the alternative identifier UGA-1785 in honor of the University of Georgia.edit Kepler-37 is a three planet system discovered by Kepler. The planet Kepler-37 c is about three quaters the size of Earth. NASA has given the planetary system the alternative identifier UGA-1785 in honor of the University of Georgia.edit Kepler-37 d is the outermost planet in a three planet system discovered by Kepler. It is twice as big as Earth and therefore the largest known planet in the system. NASA has given the planetary system the alternative identifier UGA-1785 in honor of the University of Georgia.edit The fourth planet in the Kepler-37 system was discovered by transit timing variations. Very little is known of its properties.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.
