Each star moves around the center of the galaxy it belongs to, in circular motion. But since all galaxies in the the universe are moving away from each other that will unravel the repeated circles of rotation of the star around its galaxy center into helical path on an imaginary cylinder surface ever increasing in height in one direction outward and away from all other galaxies.
Actual motion and apparent motion.
The actual motion of stars is very hard to see because stars are very far away.
Apparent motion is what it looks like it's doing from here on earth. Actual motion is what it's actually doing in space relative to the system's center, whether you're talking about the sun, if it's the motion of a planet; or the galactic center, if you're talking about a star.
Periodic, Variable, and Uniform motion.
