Document Summary
Jupiter is three times larger than saturn, the next largest planet. Jupiter is normally the 4th brightest object in the sky. It has satellites that race about it at high speed and don"t fly off into space. Io is the innermost of the four galilean satellites and its orbit is just a bit larger than the orbit of. It streaks around its orbit in less than two days, whereas moon takes a month. Jupiter must be massive to hold such a rapidly moving satellite. Jupiter"s mass is calculated to be about 318 times earth"s mass. Jupiter has hurricane-force winds and lightning bolts, as well as swirling vortex of clouds (great. Red spot) larger than earth: cosmically sized drop of gas/liquid/solid hydrogen (and helium) 318 times earth"s mass, strong winds produce the pattern, but the planet"s heat is driving force of the circulation.
