Abstract. Interest in asteroids and small celestial bodies significantly increased in the last two decades,
and, consequently, the number of space exploration missions increased as well. We propose to exploit a frequency-domain method, the harmonic balance method, as an efficient alternative to the usual time integration to carry out periodic orbital propagation around irregularly shaped celestial bodies. This method allows a quasi-direct access to bifurcation detection and the stability of the orbit.
