Visual magnitude 2.02.
The absolute magnitude of the main star in the Polaris system is -3.6
It is around the 50th brightest.
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
That refers to its actual brightness, not to how we see it. The apparent brightness depends on the real ("absolute") brightness, but also on the distance.
The absolute magnitude of Polaris is about -3.64. This value represents the intrinsic brightness of the star if it were observed from a standard distance of 32.6 light-years.
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, also known as the North Star, is approximately 2,500 times brighter than the Sun. This brightness is measured in terms of absolute magnitude, where Polaris has an absolute magnitude of about -3.6, compared to the Sun's absolute magnitude of about +4.8. However, the apparent brightness of stars can vary based on their distance from Earth.
As seen from Earth, yes, Sirius is the brightest star in the night sky. In terms of actual brightness, no.
Polaris, also known as the North Star, can be seen during the day under specific conditions, such as when the sky is exceptionally clear and the sun is low on the horizon. This is typically around sunrise or sunset when the brightness of the sun is less intense. However, due to its brightness and position, it's often difficult to spot during daylight hours. Generally, viewing Polaris is best done at night when it is fully visible against the dark sky.
I suggest you look up each of the stars - for example on Wikipedia - and decide what characteristics you want to concentrate on. Two different stars may be different in the following characteristics: mass; diameter; color; surface temperature; distance from Earth; apparent brightness; absolute brightness; and several others.
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.
