Summary
[edit]DescriptionHelene PIA06639.jpg |
English: Saturn's moon Helene, seen here with Saturn's nearly edge-on rings, orbits 60 degrees ahead of Dione and is called a "Trojan" moon. The tiny moon Polydeuces (about 5 kilometers or 3 miles across, recently discovered by Cassini imaging scientists) is also a Dione Trojan, orbiting 60 degrees behind. Helene is 32 kilometers (20 miles) across.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 12, 2005, at a distance of approximately 2 million kilometers (1.2 million miles) from Helene and at a Sun-Helene-spacecraft, or phase, angle of 90 degrees. Resolution in the original image was 10 kilometers (7 miles) per pixel. |
