View of Jupiter's moon Io from 800,000 km

Io
Voyager 1 image of Jupiter's satellite, Io, taken from a distance of 800,000 km. Io appears to be the most volcanically active body in the solar system. The circular area at the center of the image is the volcanic region Prometheus, at 2 S, 153 W. The diameter of the dark central area is about 200 km. Below that to the left is Culann Patera, and below that Mycenae Regio. Io is 3,600 km in diameter. North is at 12:30. (Voyager 1, FDS 16368.36 )
