Voyager 2 image of Jupiter's moon Ganymede from 1,230,000 km. The dark circular area at upper right is Galileo Regio, about 3,200 km is diameter. This feature is centered at 36 N, 138 W and may be covered with frost in the upper rightmost section. The bright band to the left of Galileo Regio is Uruk Sulcus. At almost 5,300 km diameter, larger than Mercury, Ganymede is the largest satellite in the solar system. North is at about 1:00. (Voyager 2, FDS 20608.11)
