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...
Lunar Perigees and Apogees in 2025 Perigee and apogee also affect the tides. During the final quarter of the 20th century, the Moon was as close to Earth as 216,500 miles (surface to surface) at its most extreme perigee and as far away as 247,700 miles at its most extreme apogee. A...

Effects of Apogee and Perigee The apogee and perigee of the moon have an effect on the tides here on Earth. When the moon is at apogee, the furthest distance from the Earth, it has less gravitational pull which, along with other factors that influence the tides, can contribute to lower...

For each perigee and apogee the distance in kilometres between the centres of the Earth and Moon is given. Perigee and apogee distances are usually accurate to within a few kilometres compared to values calculated with the definitive ELP 2000-82 theory of the lunar orbit; the maximum error ...
Moon at Perigee and Apogee: 2001 to 2100 Greenwich Mean Time Introduction 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) ...
