Document Summary
On the first loop it flew close behind venus in its solar orbit, where it "stole" some of the planet"s orbital momentum on april 26, 1998. The next loop provided a second flyby of venus, on june 24, 1999, and one of earth, on august 18, 1999. Given these three "gravity assist" boosts, cassini-huygens finally had enough orbital momentum to reach the outer solar system. The friction of the falling droplets and the compactionof them in the core heat the planet. This heating is similar to the heating produced when a star contracts: saturn and jupiter are similar in that there is no clear division between the atmosphere and the surface of the planet. Zones are higher clouds formed by rising gas, and belts are lower clouds formed by sinking gas. But the clouds are not very distinct on saturn.
