where does the name of the moon come from
Moon The usual English proper name for Earth's natural satellite is "the Moon".[12][13] The noun moon is derived from moone (around 1380), which developed from mone (1135), which is derived from Old English mōna (dating from before 725), which ultimately stems from Proto-Germanic *mǣnōn, like all Germanic language cognates.[14] Occasionally, the name "Luna" is used. In literature, especially science fiction, "Luna" is used to distinguish it from other moons, while in poetry, the name has been used to denote personification of our moon.[15]
New moon In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude.[1] At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse. Daylight outshines the earthlight that dimly illuminates the dark side of the new Moon. The actual phase is usually a very thin crescent because the Moon rarely passes directly in front of the Sun, except in a solar eclipse.[note 1]
