The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 2, 2007 at a distance of approximately 2.2 million kilometres from Saturn.

This image of Tethys was taken by the Cassini spaceprobe on July 21, 2007, when it was approximately 460,433 kilometres away.

The image was taken using the CL1 and CL2 filters.

This view of Tethys was captured by the Casssini spaceprobe on May 27, 2007 using a combination of spectral filters sensitive to wavelengths of light centred at 298 and 338 nanometers, and shows Ithaca Chasma near the centre of this image. The moon's western limb is flattened due to the rim of the Odysseus impact basin .

North on Tethys is up and rotated 24 degrees to the left.
This view looks toward the moon's Saturn-facing hemisphere.
The image was obtained with the spacecraft narrow-angle camera at a distance of approximately 267,000 kilometres from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 13 degrees.

This image of Tethys was taken by the Cassini spaceprobe on June 27, 2007, when it was approximately 27,928 kilometres away.
