images show Belinda as an elongated object with its major axis pointing towards Uranus. The moon is very elongated, with its short axis 0.5 ± 0.1 times the long axis. Its surface is grey in color.

Belinda and Cupid will probably be the first pair of moons to collide, in 100,000 to 10 million years' time depending on the densities of the Portia-group satellites, due to resonant interactions with the much smaller Cupid.
