Question
does the sun move from its position? Its true?

Answer
Every body in the universe is moving. Of course it is very difficult to define a fixed coordinate system, but if we arbitrarily take the center of our galaxy, the sun is moving relative to that center. Another point of view is that because the universe is expanding, every star including the sun is moving away from every other star. I have read that far into the future, an astronomer (if there is an astronomer) would see only a black sky at night.
