Which is bigger, the sun or the North Star?

The sun. Polaris is now in the sky, pointing to the north pole of the earth. Therefore, it always seems to be in the northern sky. It is because of its important position that it is famous. In fact, according to the brightness, it is just an ordinary second-class star, belonging to the "younger generation", more than 300 light years away from us. Polaris belongs to the brightest star in Ursa minor, also called Alpha Ursa minor, and was called "Gouchenyi" or "Beichen" in ancient China. On the constellation diagram, it is on the tip of the bear's tail. Speaking of which, maybe you have to ask: Will Alpha Ursa minor always enjoy the title of Polaris? Or, will the north pole of the earth's rotation axis always point to this star? First of all, it should be pointed out that the rotation axis of the earth is also slowly swinging periodically. Therefore, the position of the sky referred to by the north pole of the earth's rotation axis naturally changed. It can be seen that the "throne" of Polaris also has the possibility of taking turns to sit on the throne. Astronomers have figured out that 4800 years ago, Polaris was not the present alpha star in Ursa minor, but the alpha star in Draco, which was called "right pivot" in ancient China, and at that time, "right pivot" won the honor of Polaris. By the year 1000, that is, the early years of the Northern Song Dynasty in China, the sky pointed by the North Pole of the earth was 6 degrees away from the current Polaris Ursa minor, so it was far from being the North Star at that time. At present, the sky pointed by the north pole of the earth's rotation axis is only about 1 degree away from Ursa minor α, and the sky pointed by the north pole of the earth's rotation axis is approaching Ursa minor α at a speed of 15 seconds per year. By AD 2 100, the angular distance between the sky indicated by the north pole of the earth's rotation axis and the alpha star Ursa minor was the smallest, only about 28 minutes. It seems that its "status" reached the peak of Polaris at this time. In the future, the sky pointing to the north pole of the earth's rotation axis will gradually move away from Ursa minor. Around 4000 AD, the γ star Cepheus will become the Polaris, and after 14000, the α star Vega in Lyra will be honored as the Polaris. At that time, people will talk about the story of the Cowherd and the Weaver Girl again. Vega will occupy the "throne" of Polaris, and its position will far surpass that of Cowherd. It takes about 26,000 years for the earth's rotation axis to swing like this. This shows that everything is in motion, stillness is only temporary and relative, and the change of motion is eternal.
