Pericelet Moon

Japanese: 近点月 - きんてんげつ
Pericelet Moon
The time it takes for the Moon to pass perigee once and then pass it again is 27.554551 mean solar days. The Moon's perigee moves forward in a cycle that takes it about nine years to orbit the Earth, so the perigee month is longer than the sidereal month.
