Résumé
The space missions Messenger and Bepi-Colombo require precise short-term studies of Mercury's rotation. In this scope, we performed analytically and numerically a synthetic 3-dimensional representation of this rotation, using complete ephemerides of the orbital motions of the planets. In particular, we enlight the perturbations of Venus and Jupiter. Moreover, we show that a resonance between the orbital motion of Jupiter and the free libration in longitude cannot be excluded.
