7. Giant Worlds and Satellites

Joshua Barnes -- Fall 1999

Last: 6. Planets With Atmosphere Next: 8. The Sun

The outer Solar System contains two `failed stars' and two planets which are merely enormous by terrestrial standards. Jupiter & Saturn both radiate about twice as much energy as they receive from the Sun; this outflowing energy powers dramatic activity in these planets' magnetized interiors and atmospheres. Uranus & Neptune, though each about 15 times the Earth's mass, are less active. All these giants have systems of satellite and rings shaped by subtle dynamical effects over trillions of orbits, and possibly by collisions as well.
