How many other moons in the Solar System share this feature?Most of them. If the rotational frequency of satellite is larger than orbital frequency, a small torque counteracting the rotation arises, eventually locking the frequencies in a tidal lock. Pluto and Charon are the extreme example, being locked to each other.hard 43% nonenone31%oneone14%threethree9%most of themmost of them43%Created by: globalquiz.org.
