About Aquarius and Scorpio (astronomy! ! ! )

The problem is short and there are many serious injuries. It is necessary to correct some misunderstandings in order to explain this kind of problem from astronomy.

(1) There is no "Aquarius" in astronomy, only "Aquarius". According to myths and legends, Aquarius pours wine into the mouth of South Fish. The name Aquarius is directly borrowed from Japanese characters, which can only be said to be misleading.

(2) An area of the constellation on the celestial sphere has a fixed relative position, just like the four wheels of a car. No matter how cars move, the distance between them remains the same.

(3) The distance on the celestial sphere, regardless of the distance unit, is an angular unit. For example, the Cowherd and the Weaver Girl are separated by 38, which means that the Cowherd-Earth-Weaver Girl angle is 38.

So the answer given is a fixed value, expressed in angular units.

Aquarius and Scorpio are separated by Sagittarius and Capricorn. The center distance between the two constellations is about 80, the farthest distance (east of Aries and Aquarius) is about 125, and the nearest distance is about 60.
