Yes it is moving. All of the universe is expanding outwards, presumably still moving from the big bang. We have empiracal evidance that essentially proves this. The effect is called "the red shift". It refers to the shifting of wavelengths of light. We know that certain kinds of stars emit certain types of light. We have observed that some stars which should be emitting a certain kind of light are showing a differnt kind of light. This is because the star is traveling away from us and the wavelength of it's light appears shifted to us. When the object is traveling away from us the wavelength is shifted towards the red end of the spectrum. NO matter where we look we notice this shift and the shift is always towards the red end. This tells us that the universe is expanding outwards in all directions.

The whole cycle of things moving around other things is very common in this universe. For example to start with, moon around planets, planets around sun, sun around the galaxy's center..

The sun rotates and also revolves around the center of the galaxy. Our solar system is seated in the inner part of one of the arms of the Milky Way galaxy. the galaxy is spiral and is rotating on its axis. and also the galaxy as a result of the big bang is moving away from or towards some galaxies. this means that sun does move around in this vast space. I think they have even predicted the speed of the sun across the galaxy. I don't remember the numbers though and i think u can very well get it.

Yes, the sun moves in space. It orbits around the core of the galaxy as well as bobs up and down within our galactic arm.

This is just a start. We are on the outer fringe of the milky way galaxy in one of its spiral arms. I am uncertain if we are able to see our movement via the doppler shift from a fixed point elsewhere that could make that determination, but suspect we are moving outward from the center of this galaxy. I would check out a good university website to see what they have to say. Try any astrophysics site at the California Institute of Technology site or MIT.

Our planets orbit the sun. The sun orbits the center of our galaxy. As it does so, it bobs up and down out of the arm of the galaxy we are in. Further, our galaxy is moving toward our neighbor galaxy Andromeda. Put all this together and the motion is complex.

The earth is, of course, orbiting our sun. The sun orbits the center of mass of our galaxy, the Milky Way. The sun is about 26,000 light years from the center of the galaxy. It takes about 226 million years for the sun to complete one orbit of the galaxy travelling at about 486,000 miles per hour.

I dont think it moves. The planets rotate around the sun. Thats what gives the illuision of it moving is us moving around IT.

Yes it rotates around our Galaxy, the galaxy is also moving away from the origin of the Big Bang.

According to all that I have read, the solar system which is us and the other 8 planets revolve around it. I also saw on a video that it spins in one place while we are revolving it. Hope that helped some.

'some thing' might would desire to be fantastically darn vast, and shifting fantastically darn quickly, to make any important replace in the action of the solar. Even then, the solar might only draw something of the gadget alongside with it. you're thinking the opportunity of the solar encountering a rogue gasoline super. There are lots extra probable issues to rigidity approximately.
