Perdita is a moon of which planet in the Solar System
Perdita (moon) in 1999, it was given the temporary designation of S/1986 U 10. It was named Perdita (Latin for 'lost') after the daughter of Leontes and Hermione in William Shakespeare's play "The Winter's Tale". The moon is also designated Uranus XXV. The moon orbits between Belinda and Puck. The above-mentioned Hubble measurements prove that Perdita does not follow a direct Keplerian motion around Uranus. Instead, it is clearly caught in a 43:44 orbital resonance with the nearby moon Belinda. It is also close to an 8:7 resonance with Rosalind. Perdita belongs to the Portia group of satellites, which also includes Bianca,
Stability of the Solar System essentially the distance from sun to earth). These are now known as the Kirkwood gaps. Some asteroids were later discovered to orbit in these gaps, but their orbits are unstable and they will eventually break out of the resonance due to close encounters with a major planet. Another common form of resonance in the Solar System is spin–orbit resonance, where the period of spin (the time it takes the planet or moon to rotate once about its axis) has a simple numerical relationship with its orbital period. An example is our own Moon, which is in a 1:1 spin–orbit resonance
