must have an orbit that lies within the Hill sphere of the planet... have a Hill sphere of its own... The Hill sphere for Jupiter is the largest sphere... the Hill sphere describes the outer limit that an even smaller third body... The Hill sphere extends between the... of the Hill sphere for the smaller body... The Hill sphere for Earth thus extends out to about 1... relation in terms of the volume of the Hill sphere compared with the volume of the second body... quick way of estimating the radius of the Hill sphere comes from replacing mass with density in the above equation... The Hill sphere is but an approximation... show that orbits at or just within the Hill sphere are not stable in the long term... since the Hill sphere of the shuttle is only 120 cm in radius... will have a Hill sphere that can reach 220 000 km... its Hill sphere measures 22 km in radius...
