Jupiter
This image of Jupiter, Ganymede and Callisto was taken while Voyager 1 was a little over a month away (closest approach was on March 5). Ganymede is at right center and Europa is at the top right. Ganymede is larger than Mercury and looks to be composed of a mixture of rock and water ice. Europa, slightly smaller than the Moon, exhibits a very bright surface. Jupiter is 71,492 km in diameter and north is at 11:30. (Voyager 1, P-20938)
