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 · Like Earth, the Moon has a day side and a night side, which change as the Moon rotates. Moon Phases Between four and seven times a year, Earth, Moon and Sun line up just right to create the cosmic-scale shadow show known as an eclipse.

The Earth and the Moon form the Earth–Moon satellite system with a shared center of mass, or barycenter. This barycenter is 1,700 km (1,100 mi) (about a quarter of Earth's radius) beneath the Earth's surface. The Moon's orbit is slightly elliptical, with an orbital eccentricity of 0.055. [1]

3 天之前 · 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.

The moon orbits the earth in a nearly circular pattern every 27.3 days. The moon's orbit is tilted approximately 5 degrees off of the path of the plane of the ecliptic (or the path that the sun appears to trace across the sky), and orbits at a distance of almost 240,000 miles from the earth.

2019年9月25日 · As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon’s phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon’s orbital period (measured against the stars) since the Earth moves a significant ...

2023年5月23日 · Learn how Earth's moon formed, how its orbit affects Earth's tides, why solar and lunar eclipses happen and the history of lunar exploration.

2024年12月20日 · Does the Moon orbit Earth? Yes. 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.

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.

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.
