A pale and icy moon of the planet Saturn, whose diameter of more than 1,500 kilometres makes it that planet's second largest satellite, after Titan. Rhea is the outermost of five moons that orbit close to their parent planet, with the others (counting inwards) being Dione, Tethys, Enceladus and, closest of all to Saturn, Mimas. Beyond Rhea are some 700,000 kilometres of empty space before the orbit of the next moon, mighty Titan itself.
