At 150 km diameter, Puck is the largest of Uranus' lesser satellites, behind the five major satellites, all of which have diameters greater than 400 km. This image was taken on 24 January 1986 from a distance of 493,000 km. Puck orbits 58,000 km above the Uranian cloud tops with a period of 18 hours, 17 minutes. The satellite is about 130 km across in this image and the rotation axis is vertical.
