The height of the brightest star is about 40 degrees. Which star is Sirius? Of course, the premise is to exclude planets. The orbits of planets in the night sky are generally similar to those of the moon, and Sirius is lower.

Sirius, also known as Alpha Canis, is the brightest star in the whole day except the sun, but it is darker than Venus and Jupiter and brighter than Mars most of the time.

Of course, the ancients in our country also noticed this bright star and called it "Wolf Star", which is located in the south of Queqiu and the most striking star in Su Jing. In the past, this star refers to the invading aliens, and its change of light and shade indicates the security of the frontier. Therefore, for the peace of the territory, the ancients set up a bow-"arrow" to shoot wolves in the southeast of "Wolf Star". The bow composed of these nine stars is very vivid. The arrow is on the string, the bow is round, and the arrow points directly at the "Wolf Star" in the northwest.
