The discovery in recent years of non-planetary rings around some small celestial bodies has caused great interest in the problem of the origin and evolution of such rings. We consider the problem of the precession of ring located in the gravitational field of a massive rapidly rotating triaxial ellipsoid. Our method uses the mutual energy as a perturbing function in the Lagrange equations. It was found that the precession period of Haumea’s ring is 12.9 days.
