Abstract A body dissipates energy when it freely rotates about any axis different from principal. This entails relaxation, i.e., decrease of the rotational energy, with the angular momentum preserved. The spin about the major-inertia axis corresponds to the minimal kinetic energy, for a fixed angular momentum. Thence one may expect comets and asteroids (as well as spacecraft or cosmic-dust granules) to stay in this, so-called principal, state of rotation, unless they are forced out of this… Expand

Precession of a freely rotating rigid body. Inelastic relaxation in the vicinity of poles
When a solid body is freely rotating at an angular velocity Ω, the ellipsoid of constant angular momentum, in the space Ω1,Ω2,Ω3, has poles corresponding to spinning about the minimal-inertia andExpand
