Which seat is the solar system in?

First of all, we must find out what the solar system and constellations are.

The celestial bodies in the universe are constantly moving, forming celestial bodies systems at all levels. For example, the moon revolves around the earth to form the earth-moon system, and the earth is the central celestial body in earth-moon system. The earth and other planets in the solar system revolve around the sun, which is the central celestial body in the solar system. The solar system is a small part of the Milky Way. In the Milky Way, there are over 200 billion stars like the sun.

Outside the Milky Way, there are about 654.38+billion celestial systems similar to the Milky Way, which we call extragalactic galaxies. The Milky Way and the extragalactic galaxy * * * together form a main galaxy. The total galaxy is the part of the universe that people can observe at present.

In order to understand the starry sky, people imagine the universe as a sphere with infinite radius, called the celestial sphere.

In order to understand the stars, people divide the celestial sphere into several regions, which are called constellations. For example, the Big Dipper is the main part of the constellation Ursa major. According to international regulations, the world is divided into 88 constellations. Every star belongs to a constellation. For example, Polaris is a star in Ursa minor.

Therefore, the solar system and constellation are completely different concepts and cannot be confused.
