Polaris does not appear to move.
The apparent magnitude od the main star in the Polaris system is 1.98
The main star in the Polaris system, Polaris Aa, is a yellow super-giant, with a radius which is 46 +/- 3 times that of the sun. Its apparent magnitude is 1.98 but it is a Cepheid variable.
The apparent brightness of the main star in the system is 1.98 but remember that this is a Cepheid variable.
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
The only star that does not appear to move in the Sky is Polaris, the North Star. (Actually it does move in a TINY circle, but the apparent motion is too small to notice.)
Motion parallax.
mercurys motion can be like any other planets motion
The seasons are due to axial tilts of planets and the apparent motion of stars and sun on the celestial sphere is due to diurnal motion.
