Just below Saturn's equator, the gray globe of Rhea hovers against the yellow background. The equator is marked by a thin dark band, a highly foreshortened view of Saturn's ring system. Saturn's rings cast shadows on the northern hemisphere; these shadows are dropping in latitude as the seasons proceed toward northern hemisphere spring. Above the ring shadows is a tiny dark dot, a shadow cast by one of Saturn's small moons. To the lower right of the image is a dark smudge, a shadow cast by Iapetus, Saturn's outermost large moon.
