I do not know which star is the one you refer to as "Pointer Star" but Arcturus has a declination (angle above the celestial equator) of +19° 10′ 56″. If yout "Pointer Star is "Polaris" then the angular distance between these stars is (90° - 19° 10′ 56″) or 70° 49' 04"
No. Arcturus is believed to be a single star.
Arcturus is not a double star; it is classified as a single giant star, specifically a red giant of spectral type K1. However, it does have a very faint companion that is often not considered in the context of double stars due to its low brightness. This companion is not a part of Arcturus's primary system but is instead a background star. Therefore, Arcturus is primarily known as a solitary star.
Vega appears brighter than Arcturus in the night sky because it is closer to Earth, being only about 25 light-years away compared to Arcturus which is around 37 light-years away. Additionally, Vega is a hotter and more luminous star compared to Arcturus, contributing to its perceived brightness.
Arcturus, the britghest star in the Northern Hemisphere, is a highly evolved Orange-Red Giant.
Arcturus, a red giant star, is approximately 25 times larger in diameter than our Sun. In terms of volume, around 1,000 Suns could fit inside Arcturus. This significant size difference highlights the vast scale of the universe and the diversity of star types.
The declination of the star Arcturus is 19 degrees, 11 minutes, while Polaris has a declination of 89 degrees 15 minutes. Their angular separation is the distance between them, approximately 71 degrees.
Arcturus is in class A.
