Polydeuces

Polydeuces is a small moon of Saturn that shares its orbit with the larger moon Dione. It resides in a region known as a Lagrange point, specifically the L5 Lagrange point located 60 degrees behind Dione in its orbit around Saturn. Polydeuces is part of a unique pair of Trojan moons, with Helene being the other member, both occupying stable positions within Saturn's moon system. With an estimated diameter of about 2.5 kilometers (1.6 miles), Polydeuces is much smaller than Dione. Its surface characteristics and composition are less understood due to its small size and distance from Earth.
