摘要
We consider a four-body system, where three bodies, constituting a subsystem, orbit around a larger body. This paper is devoted to study the Hill stability of the subsystem using a coplanar four-body problem. Starting from the equation of zero-velocity surface for the general coplanar four-body problem, we derive two criteria of Hill stability, one of which is similar to the criterion of Hill stability in the three-body problem. These criteria are used to judge the Hill stability of the Sun Jupiter Ganymede Callisto system.
