    the sun moves, like the planets around the sun our solar system moves with all the other 100-BILLION stars around the center or our galaxy, the motions and speeds are unoticable cuase of the massive distances between us and all object around us

    EDIT - to gizmo WRONG, the center of our galaxy is occupied by a Super-Massive Black Hole, we are 26,000 light-years from the galactic center. and a comparison, there is 4.5 light-years of empty space between us and our closest system alpha-centurie. at the galactic center the distances between the stars is on average like the distance between the sun and saturn-neptune. that 10,000 times closer then the sun to alpha-centurie. nice try though

    The Sun is moving this is a fact it is proven we can work out of far stars are away from us etc on the basis of something called "red-shift" bit complicated won't bore you. Fast or slow is irrelevant here you could say it us moving slow in relation to the other stars, but you have to realise how far they are away. When we look at a star the light we see has taken years to reach us and it is going at the unimaginable speed of 300,000,000 metres per second. A metre is roughly a yard if your American.

    It is used to support the "big bang theory" which would require the Universe to be expanding which through observation it is. Of course this does not prove the "big bang theory"entirely merely support it.

    The earth which is rotating is caught in an orbit around the sun due to the suns gravitational field. In a similar fashion the moon is orbitting the Earth due to the earths gravitational field.

    Gravity is what is known as a fundamental force that exists between two bodies drawing them together. The movement of the body is inversley propotional to its mass i.e. the smaller the mass the more it moves. Believe it or not all other things being equal if you dropped an apple the Earth acually moves toward it aswell. Crazy huh?

    So the analogy before was excellent.

    If you walked in a straight line (representing the sun moving through space).

    Your friend walked in a circle round you. (representing the earths orbit).

    Another friend walked around her in a circle. (representing the moons orbit around the earth).

    You would have a pretty good picture of what was going on.

    The apple thing is to do with a guy called Sir Isaac Newton he basically invented/discovered gravity you should google him if you want more info on it.

    Hope this helps.

    The sun rotates around the center of mass of the solar system, which is within the sun, but is not at the sun's center of mass.

    The sun also revolves around the center of the Milky Way, which itself moves as well.

    So nothing in the universe really "stays in the same place."

    one thanks to comprehend the way the barrycenter of each and every of the planets revolving in an orbit relative to that barrycenter is to guage it to the electron cloud about the neucleous of the atom. The sunlight revolves relative to each and every planet orbit all mutually.that permits you to say the the sunlight is spining round it a similar way the planets are spining round. So the initial conception that the sunlight became revolving around the earth became no longer precisely incorrect.on the instant they did not take relative action heavily. The sunlight seem to stay in similar position because its planatary orbital of the shifting barry midsection between planet is purely about 480 mile from its midsection of mass.for this reason we do not see it bypass Neverthe a lot less the sunlight and planets as a gadget revolve around the midsection of mass of the galaxy so the sunlight has relative action and so similar applies to the planets.

    It doesn't! It is moving very fast! If two cars were moving at 200 mph along side each other, you might think the other car was not moving. As said above about walking the sidewalk, it is complicated, but rest assured everything is moving very fast. Google the sun!

    It does not stay in the same place.

    Our sun is moving at about 220 km/s around the center of our galaxy. Of course our galaxy is also moving, toward our neighbor galaxy Andromeda.

    I don't know how you figure it stays in the same place, because I keep seeing it go around and around.

    It is moving. It is only in the same place in relation to our point of view. Imagine your friend walking circles around you as you walk.

    Some scientists believe that it is actually moving in one direction. It is very slow, because it is huge and takes up a lot of space, but it still moves.
