        Description Wolf 1061 b is the innermost planet in a system of super-Earths located 14 light years from the solar system. It has a minimum mass of 1.36 Earth masses.edit Wolf 1061 c is a planet with a minimum mass of 4.25 Earth masses located near the inner edge of its host star's habitable zone. It is the middle planet of a system of super-Earths located 14 light years from the solar system.edit Wolf 1061 d is a planet with a minimum mass of 5.21 Earth masses located slightly beyond the outer edge of its host star's habitable zone. It is the outermost planet of a system of super-Earths located 14 light years from the solar system.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.
