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.

The brothers of Prometheus are Atlas, Epimetheus, and Menoitios

Atlas, Prometheus, and Pandora are referred to as "shepherd moons" because they play a crucial role in maintaining the structure of Saturn's rings. Their gravitational influence helps to confine and shape the ring particles, preventing them from spreading out and dissipating. By orbiting along the edges of the rings, these moons create gaps and channels, effectively "shepherding" the material in the rings. This dynamic interaction highlights the complex relationship between Saturn and its moons.
