This photo was taken on September 25, 2005 and received on Earth September 26, 2005. The camera was pointing toward Hyperion at approximately 90,604 kilometers away, and the image was taken using the CL1 and CL2 filters.

This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2006.

Hyperion is the largest highly irregularly shaped body in the solar system. It has no fixed spin axis but instead tumbles and rotates chaotically. Close-up views of Hyperion have revealed it to have an odd, spongy appearance.

Hyperion's self-gravity is not enough to crush its materials together and eliminate gaps in its interior.
