  • These moons, orbiting Jupiter, supported the heliocentric view of the solar system.
INSIGHT

Jupiter's Atmosphere and Rotation

  • Cassini observed Jupiter's bands, stripes, and the Great Red Spot, a massive, long-lasting storm.
  • He also noted Jupiter's differential rotation, faster at the equator than the poles, unlike solid bodies.
