        Description This planet was discovered by the Kepler spacecraft during its extended K2 mission, Campaign 1. Its mass has been determined through radial velocity measurements taken with HARPS, indicating it is rocky with up to 50% of the mass in a water envelope.edit This planet was discovered by the Kepler spacecraft during its extended K2 mission, Campaign 1. The radial velocity signature of this planet is masked by variations due to stellar activity, preventing an accurate mass determination.edit This planet was discovered by the Kepler spacecraft during its extended K2 mission. The planetary system consists of three transiting Super-Earths. The low-mass star is bright and nearby, which makes this system an excellent laboratory to determine the planets' masses via Doppler spectroscopy and to constrain their atmospheric compositions via transit spectroscopy. The radial velocity signature of this planet is masked by variations due to stellar activity, preventing an accurate mass determination.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.
