Kepler-37 b
Sign in to saveKepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra. , it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury. The measurements do not constrain its mass, but masses above a few times that of the Moon give unphysically high densities.
