Thread:Comments:Astronomers discover large exo-solar system/Inter-stellar?/reply

98.6% probability, yep that is pretty damn near sure, though if the planet's orbit is as close to HD 10180 as their estimate says it is (0.02 AU), that "Earth-sized planet" isn't very earth like at all, in fact it's likely hot enough to make Venus seem like a freezer! It seems like that last neptune-sized planet might hold some promise though, 1.42 AU puts it at a good distance to have habitable moons.67.142.172.25 (talk) 00:51, 26 August 2010 (UTC)
