Kepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra.[3] As of February 2013, 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.[4] The measurements do not constrain its mass, but masses above a few times that of the Moon give unphysically high densities.[5]
