Massa Lunae

Massa Lunae (M_☾, ubi ☾ est vexillum astronomicum pro Luna), est unitas astronomica massae aequalis circiter 7.35×10²² kg. Solet saepe eligi ad massam satellitum naturalium planetarum mensurandam.

Luna est magnitudine et massa quintus maximus satelles naturalis systematis solaris et designari potest satelles massa planetaria vel planeta-satelles sub definitione geophysica vocabuli.^[1] Incertitudo afficiens aestimationem constantis gravitatis universalis praecisionem massae Lunae et aliorum corporum caelestium autem afficit. Hodierna optima aestimatio massae Lunae exprimi potest 73.5 yottagrammattum, vel 73.5 Yg:^[2][3][4]

${\displaystyle M_{\mathrm {L} }=7.3477\times 10^{22}\,{\text{kg}}}$
