The apparent brightness of the main star in the system is 1.98 but remember that this is a Cepheid variable.
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.
Polaris does not appear to move.
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
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.
The main star of the system is Ursa Minor Aa which is a Cepheid Variable. Its apparent magnitude averages at 1.98
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.
Apparent magnitude of Sirius = -1.44Apparent magnitude of Polaris = 1.97To the Earthbound observer, Sirius appears (1.44 + 1.97) = 3.41 magnitudesbrighter than Polaris.1 magnitude = (100)1/6 times as bright3.41 magnitudes = (100)3.41/6 = 13.7 times as bright as Polaris
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means 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.)
