    Study Notes

    The Moons of Jupiter, Saturn, Uranus, and Neptune

    • The Great Red Spot is a giant storm on Jupiter, larger than Earth, but recently shrinking
    • Jupiter's largest moons are spherical and have interesting features, such as potential subsurface oceans on Ganymede and Europa
    • Ganymede is the largest moon in the solar system and has a magnetic field and signs of surface movement
    • Europa may have a vast subsurface ocean and experiences tidal heating
    • Io is the most volcanically active body in the solar system, with sulfur-colored lava flows
    • Callisto has the largest ring crater, Valhalla Basin, and is composed of solid rock-ice
    • Saturn is the ringed planet with the lowest average density and primarily hydrogen atmosphere
    • Saturn's rings are a system of orbiting particles of ice, dust, and small moons
    • The Cassini mission discovered water-ice jets on Enceladus and hydrocarbon lakes on Titan
    • Uranus has an axis of rotation tilted 98 degrees, and Voyager 2 found evidence of an ocean of boiling water and new moons
    • Uranus has five large moons composed of ice and rock
    • Neptune is very similar in size and composition to Uranus, with a diameter about 4 times that of Earth
