is reporting that Corot has found its first planet. I can't find an arxiv paper about this, or even a press release, but there are many here better at squirreling out data releases than me. 1.3Mj, 1.8Rj so it's a very inflated planet, 1.5-day orbit around a 'star quite similar to the Sun' might account for that. In the Monoceros field (Corot is now pointing at the Scutum/Aquila field). |

Mongo: You're correct, if "distance of the star" means "from the exoplanet," but I meant "from Earth." A star 50 light years away is (all other things being equal) just as likely as one 5 light years away to have a transiting planet. Maybe that's obvious, but it surprised me at first.

"...eclipses that can be detected are “shallower and thus the planets detectable are going to be smaller. If the periods are short enough so that we can see enough eclipses for a given planet (a process called epoch-folding) we are going to be so sensitive that we could see one earth-radii planets.”
