Asteroid rotation rates - Distributions and statistics

摘要: An analysis of asteroid rotation rates and light-curve amplitudes disclosed many significant correlations between these parameters diameter, with distinct changes occurring near 125 km, a diameter above which self-gravity may become important. It is suggested that this size range represent division surviving primordial asteroids collisional fragments. A comparison rotational family nonfamily showed the Koronis Eos families exhibit noticeable differences, considered to be due different impact conditions and/or relatively younger age for family.
