Planet Neptune and Moons(30 slides) $60

Neptune and Uranus are nearly the same size but similarities end there. Unlike Uranus, Neptune shows a wealth of activity in its atmosphere more like Jupiter. Fifteen color slides sow Neptune's blue cloud-belted atmosphere with the Great Dark Spot and white methane clouds. Two views show Neptune's major moon, Triton, with its ice lakes and active geysers. Neptune's orbital parameters, and probable cross section complete the set.
