                Description KOI-351 is the first seven planet system discovered by Kepler. It is somewhat similar to our own Solar System, but much more compact. Two independent groups have found the transits in the Kepler data, one of them being citizen scientists (PlanetHunters.org).edit KOI-351 is the first seven planet system discovered by Kepler.

                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.
