From the star’s point of view, it’s staying put (radialy). From our point of view we can say that it went arounnd that fast as long as it has nothing to do with us. Relative movement means that there is no absolute space. Although there is the rule that nothing will accelerate faster than the speed of light, one object turning around may, by definition, cause a distant object to be said to have gone around it. The idea is that it means the same thing.
This would be like saying that a child on a merry-go-round is sitting still while the universe revolves around her. It just does not work that way.
