Abstract
We report the discovery of a Saturn-sized planet transiting a V = 11.3, K4 dwarf star every 3.9 days.WASP-29b has a mass of 0.24 ± 0.02 M Jup and a radius of 0.79 ± 0.05 RJup, making it the smallest planet so far discovered by the WASP survey, and the exoplanet most similar in mass and radius to Saturn. The host star WASP-29 has an abovesolar metallicity and fits a possible correlation for Saturn-mass planets such that planets with higher-metallicity host stars have higher core masses and thus smaller radii. © 2010.
