Unusual eclipse of Saturn's moon Rhea by Dione   Unusual eclipse....   13 October 2005   The NASA/ESA/ASI Cassini spacecraft successfully completed its only fly-by of Saturn's moon Dione on 11 October 2005. In the process, Cassini captured this image of Dione eclipsing Saturn's moon Rhea.   In the picture above, the distance between Dione and Rhea was roughly 330 000 kilometres. Dione is the second densest moon of Saturn, after Titan. It is probably composed of a rocky core making up one-third of the moon's mass, and the rest is composed of water ice. It is an icy body similar to Tethys and Rhea. Cassini will make a fly-by of Rhea on 26 November 2005.      •  At Saturn and Titan (http://www.esa.int/SPECIALS/Cassini-Huygens/index.html) Huygens raw images  •  - (http://esamultimedia.esa.int/docs/titanraw/index.htm) Sounds of Titan  •  - (http://www.esa.int/SPECIALS/Cassini-Huygens/SEM85Q71Y3E_0.html) Related articles  •  Tethys drifts above Saturn (http://www.esa.int/SPECIALS/Cassini-Huygens/SEM54JG23IE_0.html)  •  The fountains of Enceladus...
