Summary
Original Caption Released with Image:
This Voyager 2 image of the Uranian rings delta, gamma, eta, beta and alpha (from top) was taken Jan. 23, 1986. The spacecraft was 1.12 million kilometers (690,000 miles) away when its narrow-angle camera obtained this clear-filter view. This image illustrates the broad outer component and narrow inner component of the eta ring, which orbits Uranus at a radius of some 47,000 km (29,000 mi). The broad component is considerably more transparent than the dense, narrow inner eta component, as well as the other narrow rings shown. Resolution here is about 10 km (6 mi). The Voyager project is managed for NASA by the Jet Propulsion Laboratory.
