FIGURE 8.5.4.- Idealized orbit of 153 Hilda in the Jupiter-Sun rotating coordinate system. Due to the 3/2 resonance, Hilda describes a triangular trajectory in a time interval of 24 yr. Due to systematic perturbations the whole orbital pattern will oscillate with an amplitude of 15° and a period of 260 yr. Points A1 and A2 are the aphelia of Hilda and also her points of closest approach to Jupiter. The distance between Hilda and Jupiter at close approach is never less than 4 AU. (From Ip, 1974a.)
