Atlas, Daphnis, and Pan
Explanation:
Atlas,
Daphnis, and
Pan
are small, inner, ring moons of Saturn,
shown at the same scale in
this
montage of images from the still
Saturn-orbiting
Cassini spacecraft.
In fact, Daphnis was discovered in Cassini images from 2005.
Atlas and Pan were first sighted in images from the
Voyager 1 and 2 spacecraft.
Flying saucer-shaped Atlas orbits near the outer edge of Saturn's
bright A Ring while Daphnis orbits
inside the A Ring's
narrow Keeler Gap
and Pan within
the A Ring's larger Encke Gap.
The curious
equatorial ridges of the small ring moons
could be built up by the
accumulation of ring material over time.
Even diminutive
Daphnis makes waves in the
ring material as it glides along the edge of the Keeler Gap.
