Which star in the Big Dipper is closest to Fuxing?

Hello, landlord, this star is called "Kaiyang"

First of all, correct that the word is "auxiliary", and its star official is also called auxiliary. There are only auxiliary stars in this star official. It is a star in Ziwei Garden, and the western name is Ursa Major 80. Although it is dark, it is close to the sun, so our ancestors always regard it as the auxiliary star of the Big Dipper, hence the name "auxiliary". It is only 1 1 sec away from Kaiyang, which is a typical physical binary star visible to the naked eye (that is, they are indeed binary star systems, which are visible to the naked eye. There are many visible to the naked eye, all of which are optical binary stars. They just look together, but they are actually separated by 108,000 miles. The distance between them is 0.25 light years, and the mutual rotation period is about 800,000 years. But people with poor eyesight can't tell the difference.

Both China and the West have noticed this star for a long time. There is an old saying in China that you can't see the salary until you see the details. Westerners say that you can see the auxiliary star, but you can't see the moon. When the ancient Arabs recruited soldiers, they used Kaiyang and Fuxi as "test stars" to test the soldiers' eyesight. It can be seen that they are binary stars and their eyesight is qualified.
