Why does the moon and earth rotate around the sun?

Answer 1

Stars are not always in the same place. Stars were drawn in a cave in France 35,000 years ago. One has moved away from where it was at that time. When the pyramids were built, The world had a different north star. The stars are moving. We simply do not live long enough to see them change position. Our lives are short compared to the few thousand years it would take to notice the difference in the position of stars.

Answer 2

the earth doesnt rotate around the moon it just rotates around the sun. that means, moon rotates around the earth, earth rotates around the sun.(i figured this out in your question 'why does the earth rotate around the sun and the moon?')

the moon rotates around the earth and the earth rotates around the sun because of the gravitational pull of the sun and the moon.

Answer 3

All orbiting bodies are acted on by gravity. It attracts them to each other. The other factor is inertia. The moon orbits the earth because it is "in motion" and its inertia, coupled with the attraction of gravity, keeps it in its orbit. The same is true of the earth and sun. Let's do a quick review.

We mentioned inertia, and an example of inertia might help us learn what's going on. If we see a weight on a string and watch it whirled around by someone holding the end of that string, we see the weight moving in a circle about the person. The weight is said to have inertia, and because its mass is moving, it carries a certain "energy" with it. This is inertia, and if the person lets go of the string, the weight continues off on a tangent from the circle it was moving in. Its inertia carried it off when the string was released.

If we consider an orbiting body as the weight and gravity as the "string" between the bodies, we have a good working model of the system. Gravity and the inertia of the orbiting body keep things moving the way they were. That's why the moon orbits the earth and the earth orbits the sun.

Answer 4

They are so incredibly far away that we have absolutely no practical experience to help us make distinctions. There are also no guideposts against which we can determine anything about the distance of stars. In the real world, and some Photography and visual arts, there are various cues that our eyes and brain interpret as distance and 3-dimensionality.

Actually, on unusually clear nights where there is little or no light pollution, the sky seems to have a wavy, undulating look to me. The brighter stars seem closer, and so where there are groups of them, there seems to be a warping of the sky toward the earth. Of course, I'm talking about the appearance of the sky, and many brighter stars are farther away than some dimmer ones.

Answer 5

The Moon orbits the Earth because of the Earth's gravitational pull. The Earth orbits the Sun due to the Sun's gravitational pull. This creates the motion of the Moon and Earth revolving around the Sun.

Answer 6

Because they're so far away from us that it takes several human lifetimes to notice that

a star has moved.

Watch a passenger jet flying over your city. It may be cruising along at 400 miles an hour,

but it's so far away from you that it seems to be moving rather slowly.

Answer 7

We're not sure what "it" you're talking about. The Moon does neither of those things (at least not directly).

At a guess, you mean Uranus, which has an axial tilt so severe that it's essentially "lying on its side". However, it doesn't really rotate "north to south". Scientists aren't absolutely certain why it's tilted so much, but the general theory is that a late off-center impact with a large (approximately Earth-sized) body gave it its unusual spin.

Answer 8

The north star is very close ... not exactly but pretty close ... to the point in the sky that the earth's north pole points to. ===> If you were standing on the north pole, the earth's axis would come out of the ground between your feet and continue through you into the sky. The north star would be straight up directly over your head, and everything else in the sky would circle around you once a day. That should be pretty easy to visualize. Now slowly, picture yourself watching the sky, while you walk down from the north pole to your house, wherever it is. The north pole still keeps pointing at the north star, and everything else in the sky still keeps doing circles around the north star once a day. But now you're down on the side of the earth, the north start isn't directly over your head any more, and the whole rotating shell in the sky looks like it's tilted over to the side.

Answer 9

It happens because the Earth rotates on a fixed axis which always points in the same direction.

(Also, the stars are very far away, so the Earth's orbit of the Sun has almost no effect on the position of the stars in the sky.)

As the Earth rotates (once every 24 hours, approximately) all the stars seem to follow fixed paths across the sky from east to west.

The points on the horizon where the Sun rises and sets do change.

That's because we orbit the Sun.

The combination of this orbit with the Earth's tilted axis affects the direction of sunrise and sunset during the year.

Answer 10

The earth orbits the sun because of the gravitational attraction of the sun and the vector momentum energy of the earth, cP.

Edit : I would say 1) The gravitational attraction between Earth and Sun.

2) The tangential velocity of the Earth. That is the Earth's

motion at right angles to the line between the Earth and the Sun.

The combination of these two things produces the orbital motion. The orbit is almost circular, but it is an ellipse.
