EFES-HAZE the idea of yahoo ansers is to answer peoples questions, there is no point going to questions to tell the person to read a book.

Answer 1

Technically the moon rotates once on it's axis every orbit of the Earth. The Sun rotates on it's axis approximately every 10 hours. The Sun is moving in the galactic plane and is not fixed. Approximate Earth circumference is 25,000. Moon takes the same time as the earth to orbit the sun +/- a bit depending on whereabouts it starts and finishes it's orbit with respect to the Earth. The Earth moves at 95,000 miles an hour and the moon can be 240,000mi ahead or in front of it or anywhere in between i.e. by a couple of hours or so either way.

Answer 2

The Moon spins on its axis once every 28 days (approximately).

The Sun's equatorial region spins on its axis every 27 days (approximately). The Sun is interesting in that, having an active, gaseous surface, different parts of the surface rotate at different rates. The equatorial region is the period most tracked because this is the period of sunspots that have an effect on the Earth's atmosphere.

The Sun orbits the center of the Milky Way galaxy. All of the stars in the Milky Way galaxy orbit the galaxy's center.

The circumference of the Earth's equator is 6387.137 kilometers (WGS-84 constant).

The Moon takes about 365.25 days to orbit the Sun, the same as the Earth. Actual time varies since the Moon will only complete about 12.9 orbits around the Earth in a year. That means it can take up to a couple hours longer for the Moon to complete an orbit than it takes for Earth (it could take the same amount of time or a little bit less depending upon where the Moon was in its orbit at the start of the year).

Answer 3

Does the moon spin on its axis?

Yes, it does. It used to spin faster but now because of gravity effects from earth, it slowed down considerably. It now spins on its axis once every time it orbits the earth. Its spin is synchronised with its orbit.

Does the sun spin on its axis?

Yes it does also. By examing the sun sports on the sun, it can be seen they rotate around the sun's axis.

Is the sun moving in an orbit or is it fixed?

The sun is moving in a path but no one can really tell where it is moving.

what is the circumferance of the earth around the equator?

radius of the earth=6370km. Circumference=2 x pi x 6370km = 40023.89km.

Does the moon take 365.25 days to orbit the sun?

The moon does not orbit the sun. It orbits the earth, but it follows the earth arond the sun.

Answer 4

Yes... (otherwise how would the same side face us all the time?)

Yes...

It moves along the same 'orbit' our entire solar system makes around the Milky Way

Roughly 25,000 miles

The moon doesn't orbit the sun, it orbits the Earth.

Answer 5

via fact the Earth rotates 15 tiers an hour in an easterly path making all the different celestial our bodies seem to be shifting west. additionally; The Earth strikes some million degree easterly in line with day in that is orbit around the sunlight, it rather is why constellations seem to go west over countless weeks. additionally; The moon strikes easterly in that is orbit around the Earth. for that reason it sounds as though 12 and a million/2 tiers east of a given factor on a similar time each night. yet as quickly as noted the moon looks to go west via fact the Earth is rotating easterly. yet remember! The moon is likewise in an easterly orbit via fact the Earth rotates below it.

Answer 6

Why not buy a book on astronomy?

It would be an interesting read, also, you could find out the answers by yourself.
