The Moon's orbit around Earth is elliptical. The point of the orbit closest to Earth is called perigee, while the point farthest from Earth is known as apogee. The difference between apogee and perigee. timeanddate.com Your Moon guide for February 2025 Elliptical Orbit The Moon's orbit arou...
The table presented here gives the date and time (Greenwich Mean Time) of all perigees and apogees of the Moon for the century 2001 to 2100 (for the years 1501 through 2500, see Perigee and Apogee by Century). The Moon's geocentric distance and apparent diameter (arc-minute) are given...
The Moon's actual distances at apogee and perigee can vary by several percent due to the gravitaional perturbations of the Sun on the Moon's eccentric orbit. Over the 5000-year period from -1999 to 3000 (2000 BCE to 3000 CE), the distance of the Moon's perigee varies from 356,355 t...

This means the apparent size of the Moon can vary from 29.3’ to 34.1’ — a difference of almost 5’ — from perigee to apogee. And that’s not taking into account the rising “Moon illusion,” which is actually a variation of an optical effect known as the Ponzo Illusion. And ...

Moon's Perigee and Apogee The Moon revolves around Earth in an elliptical orbit with a mean eccentricity of 0.0549. As a result, the Moon’s distance from Earth (center-to-center) varies with mean values of 363,396 km at perigee (closest) to 405,504 km at apogee (most distant). ...
