The apparent magnitude od the main star in the Polaris system is 1.98
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means variable).
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
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.
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
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
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
it has an apparent magnitude of 2.1
-3.64 is the absolute magnitude of Polaris.
That object is easily visible with a pair of binoculars. A star's apparent brightness is exactly 100 times less than another star if its apparent magnitude is +5 greater. So, the star of magnitude 7.3 appears 100 times fainter than a star of magnitude 2.3. (Polaris is a bit brighter than magnitude 2.3).
The apparent magnitude of Neptune is 7.8
Vega has an apparent magnitude of 0.03.
