Abstract:

The magnitude of the perturbations in the motion of an asteroid by Jupiter is dependent upon the minimum separation of two bodies, the degree to which the ratio of the mean motions departs from exact commensurability, and the magnitude of the eccentricity of the orbit of the asteroid. Hill in 1873 suggested that those asteroids which lie at the outer edge of the Hecuba group, which have mean motions which are nearly double the mean motion of Jupiter would furnish an accurate means of evaluating the mass of Jupiter. With recorded observations extending from April 12, 1861 until late 1966, an investigation of the validity of Hills suggestion was begun. The objective of the study is to obtain a value for the mass-ratio of the Sun to Jupiter and to obtain a definitive orbit for the minor planet Cybele. Author
