  1. Jupiter Mohr4merica, Big Purd, Danimals, and Volleyball dude

  2. Basic Properties • Tilt: 3.13° • Rotation: counterclockwise • Day: 9h 56m • Year: 12 earth years

  3. Basic Properties (cont.) • Distance from Sun: 483,800,000mi • Day: -121°C, Night: -163°C • Mass: 1.8986e27 kg (318x earth’s mass) • 11x diameter of earth • Density: 1.326 g/cm³ (<1/4 earth’s density) • Could fit 1,321 earths inside Jupiter

  4. Composition • Dense “rocky” core surrounded by a deep metallic hydrogen liquid layer • with a gaseous atmosphere (hydrogen and other gases, some unknown)

  5. Atmosphere • Clouds of ammonia crystals above • Underlying water clouds allow for lightning storms • Upwelling gaseous currents (white bands) • Downwelling gaseous currents (brown/red bands)

  6. Rings • Inner torus of particles called the halo • Bright inner ring and outer gossamer ring composed of dust (opposed to the ice that saturn’s rings consist of)

  7. Surface Features • Constant atmospheric storms • Great Red Spot—the anticyclonicsuperstorm

  8. Moons • 67 satellites, yet only 16 are greater than 10km across • 4 Galilean moons Io, Europa, Callisto, Ganymede

  9. Galilean Moons

  10. Galilean Moons (cont.) • Some scientists hypothesize a possibility of life on the moon europa. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably serve as an abode for extraterrestrial life. • The likely presence of an ocean within callisto indicates an existence that could harbor life.

  11. Fly-by Missions • The Pioneermissions obtained the first close-up images of Jupiter's atmosphere and several of its moons. • The Voyager missions vastly improved the understanding of the Galilean moons and discovered Jupiter's rings. They also confirmed that the Great Red Spot was anticyclonic. Volcanoes were found on the Io’s surface, some in the process of erupting. • The Cassiniprobe, en routeto Saturn, flew by Jupiter and provided some of the highest-resolution images ever made of the planet. • The New Horizon probe flew by Jupiter for gravity assist en route to Pluto. The probe's cameras measured plasma output from volcanoes on Io and studied all four Galilean moons in detail.
