The planet, found with the COROT satellite and dubbed COROT-9b, lies 1,500 light-years from Earth and never gets closer to its star than Mercury’s average distance from the sun. That puts the surface temperature of the planet in a relatively temperate range, somewhere between 250 kelvins and 430 kelvins (-23˚ to 157˚ Celsius). Although the gaseous planet isn’t expected to be habitable, its atmosphere could contain water vapor.

If this Jupiter-like planet has a moon, that satellite’s rocky surface could be habitable, says Sara Seager of MIT. But a planetary system closer to Earth would offer a better chance of searching for the tiny gravitational tug of such a moon, Seager adds.

“This discovery adds weight to the fact that we know that planets often orbit in or close to the habitable zone, so we should not be surprised when the Kepler or COROT satellites or some ground-based search makes the claim for the first habitable Earth or super-Earth,” comments Alan Boss of the Carnegie Institution for Science in Washington, D.C.
