How does the Moon look like from different latitudes of the Earth?
2018年1月25日 · The Moon is visible during the day, so I do not understand the second sentence. For the rest of the comment, I suggest that you choose a day when the Moon is closer to the Sun and run the simulations. For example, choose a day when the Moon is within 3 or 4 days of New Moon, and watch the Sun and Moon as they cross the sky.
Why does the Moon rotate around the Earth? - Physics Forums
2011年1月30日 · Does the Moon rotate around the Earth at a constant speed? Yes, the Moon rotates around the Earth at a constant speed. This is because of the laws of physics, specifically the law of conservation of angular momentum. How long does it take for the Moon to complete one rotation around the Earth? The Moon takes approximately 27.3 days to complete ...
Does the moon rotate on its axis? - Physics Forums
2016年6月2日 · Does the moon rotate in the same direction as Earth? Yes, the moon rotates in the same direction as Earth, counterclockwise when viewed from above the North Pole. How does the moon's rotation affect its phases? The moon's rotation does not affect its phases. The phases of the moon are determined by its position relative to the sun and Earth ...
Unraveling the Mystery of the Moon's Non-Spinning Rotation
2004年2月7日 · The debris orbitted the Earth and beganm to form the moon. Whilst the moon was forming, not only was the debris affected by the forming moon, but by the Earth's gravity. As a result one side of the moon is heavier and this has 'calibrated' the moon's orbit so that it always faces the earth. The moon does 'spin' in a way.
astrophysics - Why is the Moon's orbit so complicated?
2020年6月12日 · The pair of points at which the Moon's orbit crosses the ecliptic plane (the orbital nodes) slowly rotate around the earth every 18.6 years or so. (When one of the nodes passes between the Earth and the Sun and the moon passes through either of the nodes, then you get a solar or lunar eclipse.) The Moon will be at maximum angular deviation from ...
Changing Appearance of the Moon During a Single Night
2017年4月3日 · If you take a line from the middle of the terminator, but at 90 degrees to the termination, it more or less points towards the sun. Now consider the moon at first quarter: as the moon rises, the sun is due south, so imagine a line from the moon to the sun, and the terminator will be at 90 degrees to this, so pointing from bottom right to top left.
What if Earth’s moon started rotating? - Astronomy Stack Exchange
2022年1月23日 · Eventually the Moon became tidally locked, and as it continues to move outward, it will continue to rotate slower and slower, maintaining the spin-orbit resonance. Your scenario: The Moon's new spin period would create a time-lagged tidal bulge, and the Earth's gravity would pull on that bulge until the spin-orbit resonance was restored.
Moons with synchronous rotation in our solar system
2021年7月2日 · How massive the planet is. The time needed to tidally lock a moon is inversely proportional to the square of the mass of the planet. The giant planets have a large number of tidally locked moons. The Earth has one tidally locked moon, Mars has two, and Pluto has one. (Pluto is also tidally locked with Charon.) How large the moon is.
orbit - Does the Moon really go around the Earth? - Astronomy …
2024年11月2日 · The trajectory of the centre of mass of the Earth and Moon may be approximated by an ellipse. The actual trajectory of the moon is more complex and is perturbed by the sun, the non-spherical shape of the Earth, the other planets and other more minor effects (including a correction for Relativity). So the moon really does go around the Earth.
orbital elements - Help me better understand how the plane of …
2022年9月12日 · The Moon's plane of orbit also precesses around this same imaginary vertical axis, which is the 18.6 years cycle. However, the Moon's plane of orbit and the Earth's equatorial plane are (at least to very good approximation) independent of each other. $\endgroup$ –
