Moon key data The Moon, Earth’s sole natural satellite, constitutes a critical reference body for comparative planetology due to its well-preserved geological record and dynamically coupled evolution with Earth. Its mean geocentric distance of 384,400 km varies between363,300 km (perigee) and 405,500 km (apogee) owing to its orbital eccentricity (~0.055). These variations modulate tidal amplitudes
