Janus in the Way
Date: 21 Jan 2011
Saturn's moon Janus obscures part of the planet's A ring as the Cassini spacecraft looks toward the main rings and the thin F ring.
Janus (179 km, or 111 miles across) appears as a dark oval to the left of the center of the image. A star can also be seen on the right of the image, beyond the thin F ring.
This view looks toward the northern, sunlit side of the rings from just above the ringplane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera. The view was acquired at a distance of approximately 2.6 million km (1.6 million miles) from Janus. Image scale is 15 km (9 miles) per pixel.
