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.

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.

2024年12月20日 · The Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from new moon to new moon). As the Moon completes each 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun.

2021年6月17日 · When the moon is closest to Earth, its rotation is slower than its journey through space, allowing observers to see an additional 8 degrees on the eastern side. When the moon is farthest, the...

2025年1月30日 · 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 …

The Moon makes a complete orbit around Earth with respect to the fixed stars, its sidereal period, about once every 27.3 days. [h] However, because the Earth–Moon system moves at the same time in its orbit around the Sun, it takes slightly longer, 29.5 days, [i] [72] to return to the same lunar phase, completing a full cycle, as seen from Earth.

2021年6月28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.

2017年10月6日 · The Moon rotates as it orbits the Earth. The radial yellow line marks the 0° longitude meridian on the Moon.

2023年1月24日 · It takes 27.3 days for the moon to rotate once on its axis, while it takes 29.5 days to complete one revolution around Earth. This means that by the time the moon completes one rotation, it has only orbited around Earth once, …

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.
