Q: How often does the phenomenon of the giant moon occur?

The Answer

Last update 2022.08.10

In some years, the giant moon event occurs three or four times (such as 2022), and in a few cases (such as in the years 2029 and 2033) there can be up to five, and they always appear in succession.

This frequency occurs because a full moon is considered a giant moon if its distance from the Earth is equal to or greater than 90% of the distance from apogee to perihelion, so there can be more than one giant moon in each year.

Retired NASA astronomer Dr. Fred Espenk has created a website that provides lists of all the giant moons from the years 2000 to 2100. ( website via this link ).
