Orbit of the Moon the Moon varies as it orbits Earth and hence is not always equal to the Moon's rotational velocity. When the Moon is at its perigee, its rotation is slower than its orbital motion, and this allows us to see up to eight degrees of longitude of its eastern (right) far side. Conversely, when the Moon reaches its apogee, its rotation is faster than its orbital motion and this reveals eight degrees of longitude of its western (left) far side. This is referred to as "longitudinal libration". Because the lunar orbit is also inclined to Earth's ecliptic plane by 5.1°, the
From the Earth to the Moon (film) laws. When it is discovered that Virginia has stowed away, Nicholl cooperates with Barbicane in a desperate attempt to save her. Sharpe is knocked out, and he and Virginia are placed in the safest compartment of the ship.
