Description: A review of current knowledge of this dynamical group. Overview, low eccentricity Hildas, the Schubart family, numbered Hildas of the Palomar-Leiden survey.
, Astron.Rechen-Institut, Heidelberg, Germany The papers by Schubart are available in the Internet Numerical values of characteristic parameters of Hildas There is a separate continuation Typical Hilda asteroids are captured in the 3/2 resonance of mean motion with respect to that of Jupiter. In numerical studies on the long-period evolution of Hilda-type orbits Schubart (1982, 1991) has introduced three parameters that appear to characterize an orbit during very long intervals of time, in analogy to the proper elements of orbits of non-resonant asteroids. The following sections present values of such parameters for recently numbered or corrected Hilda orbits. Some of these orbits correspond to cases of special interest. Here the abbreviations for the 3 characteristic parameters of Schubart(1982) are:
