Uranus’ Moon Portia

Uranus’ moon Portia — Portia is a moon of Uranus, named after the 2 two heroines in plays by William Shakespeare. It was discovered in 1986 by Voyager 2. Very little is known about it.

Since it is below Uranus’ synchronous orbit radius, Portia’s orbit is slowly decaying due to tidal forces and it will one day break up into a planetary ring or impact on Uranus’ surface.
