A singular crescent moon is a informed steer in Earth’s sky, yet with Saturn’s many moons, we can see 3 or even more.

The 3 moons shown here — Titan (3,200 miles or 5,150 kilometers across), Mimas (246 miles or 396 kilometers across), and Rhea (949 miles or 1,527 kilometers across) — uncover noted contrasts. Titan, a largest moon in this image, appears hairy since we usually see a cloud layers. And since Titan’s atmosphere refracts light around a moon, a crescent “wraps” only a small serve around a moon than it would on an airless body. Rhea (upper left) apears severe since a icy aspect is heavily cratered. And a tighten investigation of Mimas (center bottom), yet formidable to see during this scale, shows aspect irregularities due to a possess aroused history.

This perspective looks toward a anti-Saturn hemisphere of Titan. North on Titan is up. The picture was taken in manifest light with a Cassini booster narrow-angle camera on Mar 25, 2015.

The perspective was performed during a stretch of approximately 1.2 million miles (2.0 million kilometers) from Titan. Image scale during Titan is 75 miles (121 kilometers) per pixel. Mimas was 1.9 million miles (3.1 million kilometers) divided with an picture scale of 11.4 miles (18.4 kilometers) per pixel. Rhea was 2.2 million miles (3.5 million kilometers) divided with an picture scale of 13.1 miles (21.1 kilometer) per pixel.

The Cassini goal is a mild plan of NASA, ESA (the European Space Agency) and a Italian Space Agency. The Jet Propulsion Laboratory, a multiplication of a California Institute of Technology in Pasadena, manages a goal for NASA’s Science Mission Directorate, Washington. The Cassini orbiter and a dual onboard cameras were designed, grown and fabricated during JPL. The imaging operations core is formed during a Space Science Institute in Boulder, Colorado.
