the sun moves around the center of our galaxy. and our galaxy is moving outwards toward the center of the universe.
now there are 2 scenarios for the edge of the universe. either:
1. the universe has no bounds and is infinite in all directions.
2. or space itself was created in the big bang, meaning it has a speed of expansion. meaning it has an end. so either the rate of expansion is equal to or faster than the speed of light and nothing could pass it or the universe is a 4 dimensional object, and once you reach the end you are right back where you started.

Yes the sun moves - it orbits around the Milky Way galaxy. As for taking us to the 'edge' of the universe - if the universe is pretty much infinite, than you are always in the 'center' of the universe as you know it - we can see about 14 billion light years out with the Hubble telescope - and can see that far in all directions - there might be more stuff beyond that, but we can't see it either due to limitations with the telescope itself, or light may not have reached us from that part of the universe since it started... who knows... it would take a very looong time to reach it at the orbital velocity of the sun around the galaxy and the velocity through space the galaxy itself is traveling. the sun will burn out well before we could get 1/2 of the way to the observable 'edge' if you could call it that...

Yes the sun does move it orbits the center of the galzxy. It also moves a little becuse the planets have a really small effect on it. Well were not going to the edge of the universe.

The sun does move - it is in orbit around the centre of the Milky Way galaxy (just like all the others stars in the galaxy).
And there is no "edge" of the universe in normal human terms, so we're safe (especially since the sun and planets is gravitationally bound to the Milky Way).

All answers you got are correct. Where did you get the idea that there is an edge? And even if there was one (of course there isn't), why would the sun have to go there?

The Sun is orbiting the Milky Way galaxy at very high speed, taking us with it.

how do you know the universe has an edge?
