Tarvos Has a Prograde Orbit.

Saturn’s moon Tarvos has a prograde orbit, meaning that it travels around Saturn in the same direction as the planet’s rotation. However, Tarvos’ orbit is also egg-shaped and angled, so Tarvos is classified as an "irregular" moon. Like Saturn's other irregular moons, Tarvos is thought to be an object that was captured by Saturn's gravity and pulled into its orbit, becoming one of the planet's moons. (In contrast, scientists think that Saturn’s “regular” moons formed from the dust that surrounded the newly formed planet).
