Cassini flew by Enceladus, shown in the center of the view, at a distance of about 16,000 miles (26,000 kilometers). The terminator between the day and night sides of Enceladus (313 miles, or 504 kilometers across) can be seen on the far left of the moon, while the shadow of the eclipsing planet runs across the bottom.
Titan (3,200 miles, or 5,150 kilometers across) is in the bottom right of this image and is about 684,000 miles (1.1 million kilometers) from the spacecraft. This view looks toward the Saturn-facing sides of Enceladus and Titan. North is up. The image was taken in visible light with the Cassini spacecraft wide-angle camera on. The view was obtained at a Sun-Enceladus-spacecraft, or phase, angle of 29 degrees. Scale in the original image was 2 miles (3 kilometers) per pixel on Enceladus. The image was contrast enhanced and magnified by a factor of 1.5 to enhance the visibility of surface features.”
