Kepler Discovers Multiple Planets Orbiting a Pair of Stars

而開普勒-47c的變化值僅為0.2%。相比之下,金星過境時就可以阻擋住大約1%的太陽盤面積

Unfortunately, Kepler-47c is also larger than Neptune, which places it in the gaseous giant family of planets. Gaseous giants aren’t known for being conducive to the formation of life. That doesn’t rule on the potential for a moon that could have liquid water on it, though.
