Artist's impression of a puffy planet. Gas giants with a large radius and very low density are called puffy planets or hot Saturns, due to their density being similar to Saturn's. Puffy planets orbit close to their stars so that the intense heat from the star combined with internal heating within the planet will help inflate the atmosphere.
