Jupiter - Voyager 2

Io and southern Jupiter

Io is seen in this image near the center of the frame in front of the southern hemisphere of Jupiter. The image was taken on 25 June 1979 from a distance of 12 million km. Io's yellowish color is due to sulfur compounds. Features as small as 200 km can be resolved in this image. Io is 3640 km in diameter, roughly the size of Earth's Moon, and north is at 11:30.
