The moon has phases too Why doesn't that make us think the moon revolves around the sun too rather than around Earth?

To see all the phases of Venus is impossible in the Earth-centred model of the Solar System.
The case of the Moon is different. Simple geometry shows how you can see
all the phases if it revolves around the Earth.
If the Moon's phases were caused by it orbiting the Sun, then the Moon would
have to be millions of miles from Earth. We know the distance to the Moon very
accurately and it's obviously orbiting the Earth.
But, of course, the Moon does go round the Sun too, along with Earth, during the year.
I hope that's clear.

How long does it take the moon to revolve once?
Every 29 days nova net Actually, that is not true. The Earth rotates, making it appear like the moon revolves around the Earth once per day. But, as evident by the different stages of the lunar cycle, ie. different shapes, the moon revolves around the Earth in more than a day, rather, a 27.5 day cycle ending with a New Moon.
What is the definition of a quarter moon?
It is when on Earth we see one quarter of the moon lit up. The surface of the moon is always illuminated a little over 50% by the sun but what we see of it on Earth varies as it revolves around the Earth from none (New moon) to about 50% (Full moon) One quarter is in between.
What helped provide evidence that the planets orbit around the sun rather than the earth?
We sometimes see gibbous (nearly but not quite full) Venus. In the Ptolemaic system, we should never see more than a crescent in Venus. Because we do in fact see more, the Ptolemaic model must be wrong. The full range of phases that we see for Venus is consistent only with the idea that Venus orbits the Sun. Galileo was the first to observe the phases of Venus - and hence to find this evidence in support of the Sun-centered system - because he was the first to observe Venus through a telescope. Without a telescope, we cannot tell that Venus goes through phases.
Why do we see different phases of the moon?
They're not. Anybody, at any time, in either hemisphere, standing anywhere on the half of the earth that can see the moon, and facing the moon, sees exactly the same shape. ============================================== Another contributor disagreed. Quite viscerally, in fact. Here's what remains after cleaning it up: People in the Northern hemisphere see the "OPPOSITE" moon phase to people in the Southern Hemisphere. Also in the N. Hemisphere the moon phases change from right to left while in the S. Hemisphere the moon phases go from left to right...
What does revolution mean in space?
In the context of astronomy, rotation and revolution are rather specific. Rotation refers to the spin on the axis, for example, a day on Earth. Revolution refers to the orbit around the primary, for example, the slightly elliptical path the Earth takes around the Sun each year.
Does earth and the moon revolve around the sun?
Earth revolves around the sun and the moon revolves around earth. The moon is most closer to earth than the sun. Our moon is much to small to be considered a planet but does affect the earth with the tides.Another AnswerThe size of the moon does not affect its designation as a moon, rather than a planet.It has to do with its motion. Since it revolves around the earth, it is considered a moon. Also, for the designation as a planet, an object needs to not only revolve around the sun, but also clear out a swath of its orbit from other debris.
Why does the Sun appear to not move?
Because we are revolving around it, so imagine if you were driving in a circle around a street light it doesnt appear to move, rather you do.

When finding helped provide evidence that the planets orbit around the sun rather that the earth?
Venus progresses through phases similar to the Moon. (Galileo's improvements to the telescope meant that Venus was visible as a disc rather than a bright spot.)
What is the difference between bisexual and bio-sexual?
I am pretty sure that they are both the same thing but bio-sexual revolves around the biological aspects of the person rather than the person themselves. Hope this helped :)
What does the retrograde motion of neptune's moon Triton indicate about its origin?
Because Triton revolves around Neptune opposite its rotational direction it is considered retrograde. This indicates that it was likely a planetoid that was captured by Neptune's gravity rather than having formed in orbit around Neptune.
What is the theme of the ninny?
The theme of "The Ninny" by Anton Chekhov revolves around societal expectations and the perception of intelligence. It explores how individuals may be judged based on superficial qualities rather than their true character or abilities.
Who is the antagonist in the acorn people?

How were the final phases of the war in Europe similar to the final phases of the war in pacific?
During World War II, the final phases of the war in Europe were similar to the final phases of the war in the Pacific in several ways. For one thing, the general superiority of the Allies enabled them to initiate combat when and where they chose, rather than the other way around (as had been the case early in the war). For another thing, the Allied troops faced generally unsuccessful yet highly fanatical resistance, leading to continuing casualties and an overall extension of the war.
