Daphnis and a Little Star...

Caption NASA:"The Cassini Spacecraft captures a view showing two of Saturn's moons and their gravitational effects on nearby Rings.
At top, Daphnis (about 8 Km, or 5 miles across at its widest point) streaks through the Keeler Gap, with its ever-present edge waves. At center, Prometheus (about 86 Km, or 53 miles across at its widest point) pulls away from a recent encounter with the F-Rring. A bright background star is visible below the F-Ring.

This view looks toward the unilluminated side of the Rings from about 41° above the Ring-Plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 8, 2008. The view was acquired at a distance of approx. 1,3 MKM (such as about 788.000 miles) from Prometheus and at a Sun-Prometheus-Spacecraft, or phase, angle of 53°.
Image scale is roughly 8 Km (about 5 miles) per pixel".

Nota Lunexit: noi vediamo Daphnis, la "Piccola Stella" in basso rispetto all'Anello "F" e la scia lasciata da Prometheus (sull'estrema Sx del frame) a seguito del suo transito ma, di Prometheus...nessuna traccia! E Voi? Lo vedete Prometheus?
