| Abstract | In the inner solar system, impact craters are made mostly by asteroids and long-period comets. The Jupiter family of comets, whose comets are in relatively short-period,low-inclination orbits dominated dynamically by gravitational interactions with jupiter, is relatively unimportant. These roles are reversed in the outer solar system. Asteroids rarely reach as far as Jupiter, and long-period comets are more or less uniformly distributed. The Jupiter-family comets, which swarm about Jupiter, are relatively the most important source of cratering in the vicinity of Jupiter. The purpose of this project was to determine the absolute cratering rates on the Galilean satellites, and to use those rates to estimate surface ages on io, Europa, Ganymede, and Callisto. |
