Which is brighter, invivo or Polaris?

Polaris belongs to Ursa minor and Invivo belongs to Antarctica. Polaris is 20 times brighter than invivo. Alpha, the Polaris Ursa minor, is 20 times brighter than it. When you go to the South Pole, you won't find invivo, because there are no bright or semi-bright stars in that sky. In addition, there is a beta star near the south celestial pole and Aquarius, and its brightness is about 1/3 lower than that of Polaris.

Introduction to invivo

The Antarctic horse is invivo, which is considered as the current Polaris relative to Polaris. For an observer in the southern hemisphere, the Antarctic σ is almost motionless, and all the stars in the southern sky seem to revolve around it. It is a small semi-hexagon, part of the ladder, only 1 degree away from the real South Pole, but because of precession, the South Pole of the celestial sphere is gradually moving away.

Although the Antarctic constellation σ is often called the north star in the south, the official will never agree with this name, even if the term is invented in modern times.
