The Moon can also occult planets. These occultations are even rarer.
Rarest of all is an occultation of a star by a planet and one planet occulting another.

Transits of Mercury occur about 13 times per century; 9 in November and 4 in May. The transit is not visible to the naked eye and must be viewed by projection.
Transits of Venus only occur in June and December. A pair of transits is separated by 8 years but each pair occurs after 105 or 121 years. A transit of Venus can be seen with the naked eye if a filter is used. They are so rare that none occurred in the 20th Century.
