Phobospotato is a misshapen
potato moon of Marsball with an average radius of 11 km. His orbit is steadily decaying, and he'll either crash into Marsball or break up into thin but vibrant rings.
He also has one of the lowest albedos in the Solar System, at ~0.071.
Orbit - Rotation
PhobosPotato has an equatorial orbit, which is almost circular. It orbits once every 7 hours 39 minutes just 5989 km above the surface of Marsball. Its orbit is decaying by 1.8 cm per year, so it is expected to crash into Marsball, or break up to leave a ring of fragments around the planet, within 100 million years.
