Details

Atlas is a small inner moon of Saturn with a broad, smooth equatorial ridge that gives it a flying-saucer shape. The ridge is probably built from ring particles swept up near the edge of Saturn's A ring.

Atlas orbits just beyond Saturn’s A ring and has a broad equatorial ridge that Cassini resolved as a smooth band around a pointier central body. Spectral mapping found ring material on its surface, supporting the interpretation that particles accumulated around the equator. Its unusual shape is a product of the ring environment it orbits in.

About

Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.

Guides explain selected parts of that range, while focused views filter the objects by subject.
