Last update 2022.08.10

<p style=";text-align:left;direction:ltr">In some years, <strong>the giant moon</strong> 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.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> 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.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Retired NASA astronomer Dr. Fred Espenk has created a website that provides lists of all the giant moons from the years 2000 to 2100.
