Evolution of the obliquities for ten asteroids

Using the method developed by Laskar and Robutel (Nature 361, 608–612, 1993), the evolution of the obliquities of ten large asteroids is investigated. These are compared with a frequency analysis. Generally, the orbits of the asteroids in the sample have orbital evolutions with characteristic frequences higher than the typical precession frequencies, No indication of chaos is found during the 2 Myr exammed for any initial obliquity of the objects.
