    Alternative planet names GJ 1214 b, Gj 1214 b, Gl 1214 b
    Description Gliese 1214 is a red dwarf in the constellation Ophiuchus only 40 light years away. The planet was found with a 40cm telescope and commercially available cameras. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. GJ1214b represents a new type of planet, like nothing seen in our solar system or any other planetary system currently known.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.
