                    Description Mercury is the innermost planet in the Solar System. Venus is the second planet from the Sun. Earth is the only known planet able to sustain life. Mars is named after the Roman god of war and often called the red planet. Jupiter is two and a half times the mass of all the other planets in the Solar System. Saturn is best known for its extensive ring system. Uranus is visible with the naked eye but has never been recognized as a planet by ancient observers. Neptune is the fourth largest planet in the Solar System. Pluto is officially categorized as a minor planet by the International Astronomical Union.

                    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.
