This is a montage of pictures from the vicinity of Jupiter, the largest planet in the solar system. Jupiter is the large object in the background. From farthest to nearest, the other objects are Io, Europa, Ganymede, and Callisto, the four largest moons of Jupiter.
In many ways, Jupiter and its moons are like a miniature solar system, ranging from rocky bodies on the inside to icy bodies on the outside, all orbiting around a much larger central object.
PtyS 106 is the course that talks the most about Jupiter and its moons.
PtyS 403, PtyS 407, and PtyS 411 also partly deal with Jupiter.
