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.
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
Actual motion and apparent motion.
Accelerates the motion of an object.
The apparent daily motion of the sun is from east to west due to the rotation of the Earth on its axis.
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means variable).
Arcturus is orange in color, and has a mass of 2.188E30 kg. Vega has an apparent magnitude of 0.03, a white color, and the size is unknown. Comments. That answer does not fully answer the question. For example there's nothing about Polaris.
