Exoplanetary Scratchpad |
A stellar binary believed to contain the planet with the biggest known diameter and the least dense. This would have been only the second planet with such a low density. Later measurements showed it wasn't that inflated, and has the expected radius for a highly irradiated core-less Hot Jupiter.
