This exoplanet is an interesting find. I note that Gliese 581 also has a Jovian that orbits even closer to the star than 581c's 0.071 AU. Which is interesting because such close Jovians are supposed to form further out and spiral in towards the star -- which is supposed to "clear out" any terrestrial worlds on the way, destabilizing their orbits. And yet here's 581c....
I suppose it's possible 581c also formed in the outer system and spiralled inward -- which would suggest it's an icy world.
