Resumen: A normalized averaged (integrable) Hamiltonian approximation is used to study the attitude dynamics of a rigid body satellite in a gravity field, with an emphasis on bifurcations. The phase portrait is represented in a Mercator map and on a 3D sphere. Pitchfork bifurcations and degeneracies (a dense set of equilibria) are found.
