At closest approach, Cassini flew within 4,330 miles (6,968 kilometers) of Helene’s surface. It was the second closest approach to Helene of the entire mission. This I found on Tom’s Astronomy blog. Got to love the image. Saturn has so many moons it is hard to keep track of them all. What I like about this image is its clarity, the patterning on the moons surface and the light and shadow effects.
