What is the name of a bright red star in the southern sky?

Arcturus, the alpha star of Capricorn, is the brightest star in Capricorn and the brightest star in the northern night sky (Sirius and Laonian are the stars in the south), and its brightness ranks fourth in the whole day, being a 0-star (not a 1-star).

Because the second and third bright stars are too far away from the South Pole of the Earth, for most observers in China, arcturus is the brightest star in the sky after Sirius disappears.

A pentagon consisting of several stars with medium brightness looks like a big kite. The brightest arcturus in this constellation (apparent magnitude is-0.04m) looks like a bright lamp hanging under a kite. Arcturus is one of the three brightest stars in the northern sky (the other two are Vega and Capella), and people call it "the most beautiful star among all the stars".

The ancient Greeks imagined the map of the patriarch as a fierce hunter, with a spear in his right hand and a high left hand, eager to catch the big bear in front of him. Every day in late spring and early summer, the patriarch is above our heads, which is the time when young hunters are full of ambition and the most proud.
