Question
Jack Wisdom's 1982 doctoral thesis hypothesized that a pattern in the distribution of these objects was caused by Arnol'd diffusion. A Russian-Polish railroad engineer pioneered work on a thermal force exerted on these objects that was added to models in CNEOS's Sentry-II software. OSIRIS-REx measured aspects of the Yarkovsky effect on one of these objects, which comprise the Hilda group. MMRs of (*) 3-to-1 and 5-to-2 correspond, respectively, to the semi-major axes 2.5 and 2.82 AU of the largest Kirkwood gaps in the distribution of these objects, which are exemplified by the dwarf planet Ceres. For 10 points, name these astronomical objects that appear between Mars and Jupiter in a namesake "belt." ■END■
