- Inclination to Saturn's Laplace plane
- 0.20 °
- From JPL orbital elements · The Laplace plane is the one a moon's orbit precesses about: close in it is the planet's equatorial plane, the plane of the rings, and further out it tilts toward the planet's own orbit.
Radiation & temperature
- Insolation
- 0.0112 S⊕ · 1% of the sunlight Earth receives
- Computed from the distance to the Sun (inverse-square; Earth's sunlight = 1), before any atmosphere.
Discovery & history
- By
- Cassini Imaging Science Team
Polydeuces was discovered in 2004 by Cassini Imaging Science Team. Saturn's moons are named after the Titans, giants and monsters of Greek and Roman myth. Beyond its discovery and naming, little more about it has been individually recorded.
