Can you spot a third moon?

In this image, captured by NASA’s Cassini spacecraft,
Saturn’s moon Enceladus appears above the rings and the
moon Rhea is below. Where is a third moon? Find the
comparatively tiny speck of Atlas above and to the left of Rhea
– about two Rhea-diameters away – just above the thin line
of Saturn’s F ring.
This view – taken on September 24, 2015 – looks toward the
unilluminated side of the rings from about 0.34 degrees below
the ring plane, at a distance of approximately 1.8 million
miles (2.8 million kilometers) from the moon Rhea.
