Atlas, Prometheus, and Pandora are referred to as "shepherd moons" because they help maintain the structure of Saturn's rings through their gravitational influence. These moons exert tidal forces that can clear gaps in the rings or confine ring material, creating distinct edges or waves. For instance, Atlas confines a ringlet within its orbit, while Prometheus and Pandora help define the boundaries of the F ring. Their interactions with the ring particles illustrate the dynamic relationship between moons and ring systems.

Atlas, Prometheus, and Pandora are referred to as shepherd moons because they help maintain the structure and boundaries of Saturn's rings. Their gravitational influence keeps the ring particles in place, preventing them from spreading out and disrupting the ring system. For instance, Atlas confines the A ring's outer edge, while Prometheus and Pandora operate as shepherds of the F ring, creating and maintaining its distinctive shape and features.
The brothers of Prometheus are Atlas, Epimetheus, and Menoitios
