Neptune and Triton

Photo: Neptune and moon Triton
Neptune's largest moon, Triton, hovers beneath the planet in this image taken by Voyager 2 in 1989. Triton is the only large moon in the solar system that has a retrograde orbit, meaning it circles its planet in a direction opposite to the planet's rotation.
