Why does the Moon appear to rise and set?

The moon rises in the east and sets in the west, each and every day. It has to. The rising and setting of all celestial objects is due to Earth’s continuous daily spin beneath the sky. Just know that – when you see a thin crescent moon in the west after sunset – it’s not a rising moon.

Does the Moon rise or Earth rotate?

east
The same holds true for the moon. It is the Earth’s rotation on its axis that makes the moon rise in east and set in the west.

Does the Earth rise and set on the Moon?

Because one side of the moon always faces us, from most places on the moon, Earth doesn’t appear to rise or set. Instead, from a given point on the moon’s near side, you’d always see Earth hanging in your sky.

Why does the Moon set in different places?

The answer is that the moon is moving. So the moon’s motion has two parts to it. It looks like it’s moving around the earth once per day along with everything else, but in addition to that it is actually moving around the earth once per month. That is what makes it move to a different place on the sky.

Why does the Moon set so early?

The Moon is continually moving on ahead in its orbit while the Earth rotates. Because the Moon has moved 13 degrees or so since its last moonrise, it’s going to take another hour or so for the Earth to catch back up to the Moon’s new location, delaying the Moon’s rising above your horizons by ~50 minutes each day.

How long does it take the Earth to rise and set on the Moon?

As the Moon orbits Earth, it always keeps the same side facing us. This, combined with the fact that it takes 29 1/2 days to complete one cycle of phases, means that anyone on the Moon’s surface would see 29 1/2 days go by between consecutive sunrises or sunsets.

Why is the moon not setting?

Just like the Sun and the night time stars, the Moon’s apparent rising in the east and setting in the west each day is not from the Moon’s orbit around the Earth, it’s from the Earth spinning. As it rises at a later time, the Moon appears in a different part of the sky.

Does Moon never rise?

It’s often said to depict an Earthrise as seen from the moon. As seen from any one spot on the moon’s surface, however, the moon doesn’t rise or set. Instead, because one side of the moon always faces Earth, from a given spot on the moon, Earth always hangs in one spot in the lunar sky.

Why does the Moon Rise and set at different times?

The time of day that the Moon rises or sets depends on its phase. This should be obvious when you remember that the phase of the Moon depends on the relative positions of the Sun, Moon and Earth. So when the Moon is new, it rises and sets with the Sun, and the position of Moonrise/set varies just like that of Sunrise/set.

How does the phase of the Moon depend on the Sun?

This should be obvious when you remember that the phase of the Moon depends on the relative positions of the Sun, Moon and Earth. For example when the Moon is Full it is opposite the Earth from the Sun, so when the Sun sets, the Moon must rise and vice versa.

Does the Moon move around the Earth in a revolution?

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.

How much difference is there between moonrise and moonset?

There has been as much as 25 degrees or more difference in the spot that the moon clears the horizon from one evening to the next. The position of Moonrise and Moonset, like that of Sunrise and Sunset varies as the Earth goes around the Sun, but also with the phases of the Moon.
