Why does the moon change location in the sky from one year to the next?

Answer 1

Because it orbits the earth. When the moon is between the earth and sun, it is back lit and appears new. Two weeks later, when the moon is on the other side of the earth and as far from the sun as it can be, it appears full from earth. As it transitions from one of these to the other and then back again, the new moon waxes to fullness then wanes to newness again.

Answer 2

The changing location of the moon in the sky from year to year is due to the moon's orbit around the Earth. As it orbits, the moon's position relative to the Earth and the sun changes, leading to variations in its appearance and position in the sky. These changes create the phases of the moon and alter its trajectory across the sky.

Answer 3

because it rotates as well as earth

and sometimes it looks like different every night

it is because everynight different stars are in the back of the star that makes the moon look like changing apperance

Answer 4

The Earth moves around the Sun in an ellipse (for more details, do some reading on Kepler's Laws); the ellipse in this case is fairly close to a circle; the average distance to the Sun is about 150 million kilometers.

Answer 5

The positions of the planets change from week to week, but the relative positions of stars - justifiably called the "fixed stars" in celestial navigation - doesn't vary from one year to the next. Only something spectacular like a nova either blossoming from invisibility, or an existing visible star blowing itself to oblivion can change the arrangements of the stars.

Which is not to say that the stars don't move - they DO. It's just that the movement is so vanishingly slow that lifetimes would pass before anyone would notice. This is because the stars are so incredibly far away that we can't notice the difference.

Answer 6

The moon revolves around the earth, every 27.3 days. It can be in the same direction

as the sun, or directly opposite the sun, or anywhere in between. We build our clocks

to track the sun, so at the same clock-time on different days or night, the moon can

be in many different positions in the sky.

Answer 7

They don't "change places". The Earth orbits the Sun and the Moon orbits the Earth. The combination of these motions makes it appear to us, standing on the surface of the Earth (which is itself rotating), as if the Sun and Moon move in the sky. (The Moon actually does move, but much more slowly than it appears to, because the Earth spins on its axis in slightly under 24 hours, and the moon takes a bit over 27 days to go all the way around the Earth.)

Answer 8

Well to put it simply,the moon and the sun positions in correlation with the earth changes the tides in the water and on land..( Fun fact: Did you know that if the tides happen at just the right moment it can trigger a earthquake?)

Answer 9

The distance between the Sun and the Earth varies, just a bit, from day to day throughout the year. On about January 4 each year, (this date will vary a day either way, depending on the cycle of leap years) the Earth reaches its perihelion ,or the point of closest approach to the Sun. This year of 2012, it happened at on January 5, at 01:00 Greenwich Mean Time, and the Sun was as close as 91 million miles away

The Sun's orbit is not a perfect circle; it is slightly elliptical. A half-year later on July 5 this year, the Sun reaches it's most distant point of about 95 million miles away.

Answer 10

Well, my physical geography teacher said that the sun migrates annually between the tropic of cancer and the tropic of capricorn, which are latitude at 23 and 1/2 degrees N and S. However, I've heard that it varies somewhat in reality--over time so I'm not sure if what she said is absolutely correct or why it varies. The slight variation is because the Earth 'wobbles' about its axis
