Vintage with a twist – er… tilt.⁣ ⁣ Voyager 2 captured this image of Saturn and two of its moons, Rhea and Dione, on July 21, 1981. In this picture, Rhea is below and to the left of Saturn, while Dione is directly below the massive planet.⁣ ⁣ Rhea looks itty-bitty in this picture, yet it’s Saturn’s second-largest moon! Rhea is small, cold, and airless - very similar to sister moons Dione, pictured here, and Tethys. How cold is Rhea? It’s as “warm” as -281ºF (-174ºC) in sunlit areas, ranging down to -364ºF (-220ºC) in the shade.⁣ ⁣ Rhea appeared as a tiny dot to astronomers until the Voyager (1 and 2) encounters in 1980 and 1981. The Voyager images showed that Rhea’s features could be divided into two regions: heavily cratered terrain with craters larger than 25 miles (40 kilometers) across and a second type of area in parts of the polar and equatorial region with craters less than 25 miles (40 kilometers) across. This difference may indicate there was a major resurfacing event some ...
