Star containing a transiting hot super Earth (0.036 au, 3.3 days) discovered by HARPS. The star is small, so the ratio between stellar and planet radii is large. Atmospheric analysis (the second for any super Earth) indicated that it was not covered by thick clouds. Its radius was found to be 4.3 that of Earth. Detailed observation of its atmosphere are expected to be able to tell if it was formed close to the star or further out depending on if volatiles are found. Since the atmosphere is not likely blocked by clouds, it is thought that a detailed atmospheric composition can be taken.
