The moon Hyperion tumbles as it orbits Saturn. Hyperion’s (270 kilometres or 168 miles across) spin axis has a chaotic orientation in time, meaning that it is essentially impossible to predict how the moon will be spinning in the future. So far, scientists only know of a few bodies with such chaotic spins.
The image was taken in green light with the Cassini spacecraft narrow-angle camera on 22 August 2016.
The view was acquired at a distance of approximately 326,000 kilometres (203,000 miles) from Hyperion and at a Sun-Hyperion-spacecraft, or phase, angle of 10 degrees. Image scale is 2 kilometres (1 mile) per pixel.
