I found this NASA graphic illustrating Jason Major's Universe
Today article "A Moon With Two Suns", this graphic illustrates
the known worlds of the Kepler-47 planetary system. Kepler-47 is
of note as it is the first planetary system discovered with
multiple planets orbiting two stars. (Last September I noted the
discovery of the Kepler-16 planetary system, which has only one
planet orbiting two stars.) Kepler-47c is of note for orbiting
in the habitable zone of the system. While it is likely some
kind of superterrestrial world or ice giant, Kepler-47c may
possess relatively Earth-like moons. NASA is excited. While the
inner planet, Kepler-47b, orbits in less than 50 days and must
be a sweltering world, the outer planet, Kepler-47c, orbits
every 303 days, putting it in the "habitable zone," where liquid
water might exist. But Kepler-47c is slightly larger than
Neptune, and hence in the realm of gaseous giant planets,
difficult to imagine as suitable for life. That does not
preclude the chance that it has larg
