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.
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.
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
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.
Polaris, also known as the North Star, appears white to the naked eye. It has a apparent visual magnitude of around 1.97, making it one of the brightest stars in the sky. It is located in the constellation Ursa Minor (the Little Bear).
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means 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.
