Credit: NASA/JPL-Caltech/Space Science Institute The moon Hyperion tumbles as it orbits Saturn. Hyperion’s (168 miles or 270 kilometers 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 Aug. 22, 2016.
The view was acquired at a distance of approximately 203,000 miles (326,000 kilometers) from Hyperion and at a Sun-Hyperion-spacecraft, or phase, angle of 10 degrees. Image scale is 1 mile (2 kilometers) per pixel.
