Dione&Co.-PIA07628.jpgDione, Tethys and Pandora66 visiteOriginal caption:"This excellent grouping of 3 moons - Dione, Tethys and Pandora - near the Rings, provides a sampling of the diversity of worlds that exists in Saturn's Realm. A 330-Km-wide (about 205 miles) impact basin can be seen near the bottom right on Dione (at left). Ithaca Chasma and the Region imaged during the Cassini spacecraft¿s Sept. 24, 2005, flyby can be seen on Tethys (middle). Little Pandora makes a good showing here as well, displaying a hint of surface detail. Tethys is on the far side of the Rings in this view; Dione and Pandora are much nearer to the Cassini spacecraft.
Rememeber that Dione is approx. 1.126 Km (about 700 miles) across. Tethys is approx. 1.071 Km (about 665 miles) across and Pandora is 84 Km (roughly 52 miles) across.
This image was taken in visible blue light with the Cassini spacecraft narrow-angle camera on Sept. 22, 2005, at a distance of approx. 1,2 MKM (about 800.000 miles) from Saturn. The image scale is about 5 Km (approx. 3 miles) per pixel on Dione and Pandora and 9 kilometers (6 miles) per pixel on Tethys".

Dione&Co.-PIA07679.jpgProportions, dimensions, perspectives and distances...63 visiteOriginal caption:" Two of Saturn's battered, icy companions hover here, above the Ring-Plane.
To get a sense of the three-dimensional nature of the scene, note that the wide band of visible Rings is in between the two moons in this view from the Cassini spacecraft.
Mimas (397 Km, or 247 miles across, at left) is outside the far side of the Rings while Dione (1.126 Km, or 700 miles across) is outside the Rings and closer to Cassini.
The view is from just beneath the Ring-Plane and the image was taken in visible light, with the Cassini spacecraft narrow-angle camera on Dec. 18, 2005, at a distance of approx. 2,2 MKM (roughly 1,4 MMs) from Dione and 2,7 MKM (about 1,7 MMs) from Mimas. The image scale is 13 Km (about 8 miles) per pixel on Dione and 16 Km (about 10 miles) per pixel on Mimas".

Rhea_Dione-PIA09011.jpgThe "Crowded" Saturnian Sky63 visiteCaption NASA:"A string of icy moons stretches across the Saturn System in this view from nearly edge-on with the Ring-Plane.
Nearest to the Cassini spacecraft is Rhea (1528 Km, or about 949 miles across) below center; then little Atlas (32 Km, or about 20 miles across), huddled close to the narrow F-Ring. Dione (1126 Km, or about 700 miles across) floats in the distance beyond.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 8, 2007 at a distance of approx. 2,9 MKM (about 1,8 MMs) from Saturn. Image scale is roughly 14 Km (about 9 miles) per pixel on Rhea and 19 Km (about 12 miles) per pixel on Dione".MareKromium

Titan_and_Dione-PIA07644.jpgTitan & Co.66 visiteOriginal caption:"In a rare moment, the Cassini spacecraft captured this enduring portrait of a near-alignment of four of Saturn's restless moons. Timing is critical when trying to capture a view of multiple bodies, like this one. All four of the moons seen here were on the far side of the Rings from the spacecraft when this image was taken; and about an hour later, all four had disappeared behind Saturn.
Seen here are Titan (5.150 Km, or 3.200 miles across) and Dione (1.126 Km, or 700 miles across) at bottom; Prometheus (102 Km, or 63 miles across) hugs the Rings at center; Telesto (24 Km, or 15 miles across) is a mere speck in the darkness above center.
The image was taken in visible light with the Cassini narrow-angle camera on Oct. 17, 2005 at a distance of approx. 3,4 MKM (2,1 MMs) from Dione and 2,5 MKM (about 1,6 MMs) from Titan. The image scale is 16 Km (10 miles) per pixel on Dione and 21 Km (about 13 miles) per pixel on Titan".
