Neptune's Cirrus Clouds

This image shows some clouds known as "cirrus" clouds, extending for many kilometers across the face of Neptune. These clouds are very high up, for they can be seen to cast shadows on the lower clouds, whi ch are 35 miles down (164,000 feet)! (In an airplane on Earth, you would fly at 35,000 feet!)

Earth also has cirrus clouds. These are shown in the connected page next to Neptune's for comparison.
