        Description Kepler-289 b has been discovered by the Kepler spacecraft and was originally classified as a planet candidate. A new statistical analysis led by a team at NASA Ames Research Center has validated the planet with more than 99 percent confidence. Although many parameters of Kepler-289 b are still unknown, the object is highly unlikely to be a false positive.edit Although this system was previously known to host at least two planets, the third planet, PH3 c, was first spotted by citizen scientists using the Planet Hunters website.edit Kepler-289 c has been discovered by the Kepler spacecraft and was originally classified as a planet candidate.

        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.
