This view looks toward the leading side of Tethys. North on Tethys is up and rotated 32 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera. The view was obtained at a distance of approximately 684,000 miles (1.1 million kilometers) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 63 degrees. Image scale is 4 miles (7 kilometers) per pixel. The image has been zoomed in by a factor of 1.5.”
