      Description This planet is a so-called Hot Jupiter which orbits tightly around its parent star in the Beehive Cluster, a collection of roughly 1,000 stars that appear to be swarming around a common center. The planet is not habitable but its sky would be starrier than what we see from Earth.edit Pr0211 c is a super-Jovian planet in a highly-elliptical orbit. The discovery of this planet was the first time a multiplanet system had been observed in an open cluster.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.
