Lunar orbit - Wikipedia
In astronomy and spaceflight, a lunar orbit (also known as a selenocentric orbit) is an orbit by an object around Earth's Moon. In general these orbits are not circular. When farthest from the Moon (at apoapsis) a spacecraft is said to be at apolune, apocynthion, or aposelene.
Orbit of the Moon - Wikipedia
Earth and the Moon orbit about their barycentre (common centre of mass), which lies about 4,670 km (2,900 miles) from Earth's centre (about 73% of its radius), forming a satellite system called the Earth–Moon system.

Orbit of the Moon: The orbital characteristics of the Moon. Average altitude of 384,403 kilometres (238,857 mi), elliptical-inclined orbit.
Moon Fact Sheet - NSSDCA
2024年1月11日 · The orbit changes over the course of the year so the distance from the Moon to Earth roughly ranges from 357,000 km to 407,000 km, giving velocities ranging from 1.100 to 0.966 km/s.
NASA - Eclipses and the Moon's Orbit
The lunar orbital period with respect to the stars (sidereal month) is 27.32166 days (27d 07h 43m 12s). However, there are three other orbital periods or months that are crucial to the understanding and prediction of eclipses. These three cycles and the harmonics between them determine when, where, and how solar and lunar eclipses occur.
Moon Facts - NASA Science
The Moon makes a complete orbit around Earth in 27 Earth days and rotates or spins at that same rate, or in that same amount of time. Because Earth is moving as well – rotating on its axis as it orbits the Sun – from our perspective, the Moon appears to orbit us every 29 days.
5.3: Measuring the Moon’s Orbital Motion - Physics LibreTexts
The Moon’s orbit around the Earth takes approximately 28 days. Because the Moon takes 4 weeks to orbit the Earth once – it takes about two weeks for the Moon to move from new moon (on the western horizon) to full moon (on the eastern horizon.)
The Moon's Orbit and Rotation - Moon: NASA Science
2022年12月2日 · The animation shows both the orbit and the rotation of the Moon. The yellow circle with the arrow and radial line have been added to make the rotation more apparent. The arrow indicates the direction of rotation. The radial line points to the center of the visible disk of the Moon at 0°N 0°E. Download options
