Several dark spoke-like features can be seen across the broad B ring (left of planet). The moons Rhea and Dione appear as dots below and below left of Saturn, respectively. This photo was taken July 21, 1981, when the spacecraft was 33.9 million km (21 million mi) from the planet. Voyager 2 made its closest approach to Saturn on August 25, 1981.
