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.
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.
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 ...
Am I looking at the moon upside down here in the US?
2021年10月14日 · No, it does not. For planets and moons, the IAU defines the north pole as the pole that shares the same half of the celestial sphere, relative to the invariable plane of the Solar System, as the Earth's north pole, so it wouldn't matter how the Moon rotated with respect to determining the Moon's north pole, just which direction that pole was pointing.
The moon doesn`t rotate around it`s axis. - Physics Forums
2006年3月17日 · The moon actually does rotate around its axis, but it does so at the same rate that it orbits around the Earth. This is known as synchronous rotation or tidal locking, which is caused by the gravitational pull of the Earth on the moon.
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.
Why is the shape of the Moon spherical? [duplicate]
From the perspective of an object orbiting Venus, it would be quite clear that the Earth's Moon does indeed rotate about its own axis. Every object rotate about its own axis. Addressing the second premise, rotation about its own axis has nothing to do with whether an object of sufficient size becomes more or less spherical over time.
The Moon's Rotation and Why it Doesn't Spin: Theories and …
2005年4月26日 · Why does the Moon always show the same side to the Earth? This phenomenon is known as synchronous rotation, where the Moon's rotational period is the same as its orbital period. This means that the Moon takes the same amount of time to rotate on its axis as it does to revolve around the Earth, causing it to always show the same side to us.
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 ...
