Oh, you crazy moon! 🌕 Saturn's moon Hyperion is spongy, potato-shaped, and tumbling around the planet in a strangely irregular orbit. Regarded as one of our solar system's strangest objects, this moon has weak gravity and a porous, loosely packed surface. Some of its craters are filled with bright, reflective water ice; those that aren't may be as cold as -300 degrees Fahrenheit (-180 degrees Celsius). @NASASolarSystem's Cassini mission captured breathtaking images of this odd moon during its Saturn flyby in 2005. See more of them at the link in our bio! Image Description: Saturn's moon Hyperion appears like a spongy, potato-shaped rock oriented diagonally from lower left to upper right. The center of the moon is a circular, medium gray region covered with deep craters. Smoother light gray areas stretch out on either side of the center. The ends are darker gray and covered with deep craters.
