The present invention relates to a lunar circumference plate. The circumferential movement plate is made of a circular plane, the celestial sphere background plate, celestial plane, horizon, observer and time scale portion shown; Transparent lunar rotating plate showing the shape of the moon according to the phase on the lunar orbit; Cover plates capable of creating the appearance of moons and planets; Respectively. A lunar rotating plate corresponding to the middle plate and a cover plate corresponding to the upper plate are sequentially stacked in the center of the celestial background plate, and the lunar rotating plate is rotatable, and the cover plate is fixedly attached to an edge around the lower half of the celestial background plate. It is characterized by. The lunar circumference of the moon according to the present invention can easily understand the moon's time of appearance and moon time and observation time according to the phase.
