Portia (moon)

Portia is a moon of Uranus. It was discovered in 1986 by Voyager 2. Very little is known about it. It is named after the heroine of William Shakespeare's play The Merchant of Venice. 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.
