  1. Josh Waisler, Alex Pham, Alex Chen, Layton Taylor JUPITER

  2. Basic Information • Jovian • 1 year = 11.83 Earth years/4332.82 Earth days • 1 day = .41 Earth days/9.93 Earth hours • 778,500,000 km/483,800,000 miles from the Sun • -121° C during the day, -148° at night

  3. Basic Information, Cont. • 317.83 x mass of Earth • .24 x density of Earth • Tilt of ~ 3.13° • Rotates in a counter-clockwise formation

  4. Surface and Atmosphere • Essentially no surface to speak of • Composed of Hydrogen (H2), Helium (He) • Also contains bands of ammonia and other elements; however these make up less than .1% of Jupiter’s composition • Famous “Great Red Spot” is actually a storm big enough to hold 2 or 3 Earth-size planets

  5. Discovery • Known by ancient civilizations • Date of discovery unknown • Named for Roman king of gods (comparable to Greek god Zeus)

  6. Rings • Made of dust particles • 1979 J1R “Halo” • 22,800 km wide • 30,089 km away from surface at closest point • 1979 J2R “Main” • 6,400 km wide • 52,889 km away from surface at closest point • 1979 J3R “Gossamer” • 85,000 km wide • 59,289 km away from surface at closest point

  7. Missions to Jupiter • Pioneer 11 • Took detailed pictures of the planet and the GRS. • Voyager I • Took photographs and gathered information about Jupiter’s many moons. • Voyager II • Showed that the GRS is a storm; determined that Io is volcanically active • Galileo • Orbited Jupiter; found ammonia in atmosphere; showed more evidence of Io’s volcanic activity • Detected a magnetic field around Ganymede; its data revealed the possibility of subsurface water on moons

  8. The Galilean Satellites These are only four of over 60 moons. Io Europa Ganymede Callisto

  9. Io • Most volcanically active body in the solar system • Surface made up of multicolored sulfur • Jupiter’s gravity causes “tides” in the solid surface

  10. Europa • Surface mostly made up of ice • Contains more water than earth • Possible “habitable zone”

  11. Ganymede • Largest moon in the solar system • Only moon with internally generated magnetic field

  12. Callisto • Heavily cratered and ancient surface • Small craters indicate current surface activity
