Title
Tethys and Titan, Saturn satellites - Tethys and Titan - The Tethys satellite passes behind the Titan satellite. These images were taken 18 minutes apart (the first image taken is on the right) by the Cassini probe on 26 November 2009 at a distance of 1 million km from Titan and 2.2 million km from Tethys. Saturn's moon Tethys with its prominent Odysseus Crater silently slips behind Saturn's largest moon Titan and then emerges on the other side. Tethys is not actually enshrouded in Titan's atmosphere. Tethys (1,062 kilometers, or 660 miles across) is more than twice as far from Cassini than Titan (5,150 kilometers, or 3,200 miles across) in this sequence. Tethys is 2.2 million kilometers (1.4 million miles) from Cassini. Titan is about 1 million kilometers (621,000 miles) away. These two color views were captured about 18 minutes apart, with the view on the right taking place first. These images are part of a mutual event sequence in which one moon passes close to or in front of another as seen from the spacecraft. Such observations help scientists refine their understanding of the orbits of Saturn's moons. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained with the Cassini spacecraft narrow - angle camera on Nov. 26, 2009. Image scale is 6 kilometers (4 miles) per pixel on Titan and 13 kilometers (8 miles) per pixel on Tethys
