. The sharply-defined crater just above the center of this Cassini image shows layers of alternating bright and dark material. A thin dark layer on the crater wall appears to define the base of an ejecta blanket. Cassini was 8,314 miles (13,377 km) from Phoebe when this image was taken. NASA / JPL / CICLOPS
