LUNAR OCCULTATION OF PLANETS : PANORAMA 2009-2020
Conditions of visibility and various information, data elaborated with WinOccult (C)
The occultations of the planets by the Moon occur in series too,
but only for the slow planets, Jupiter, Saturn, Uranus and Neptune.
The other planets have a motion so fast respect to the nodes of the lunar orbit that
in most cases an occultation cannot repeat in the same lunar month.
The mean lenght of period between a serie and the following is smaller than the cycle
of stellar occultation, because of the motion of the planets respect to the stars is
direct while the motion of the lunar nodes is retrograde.
Frequency of series, Jupiter 7.24 year
Saturn 11.4 year
Uranus 15.23 year
Neptune 16.71 year
