What are the components of the universe, the Milky Way and the solar system? What's the difference between them? What is the constellation?

The universe is made up of time and space. There are all kinds of galaxies and black holes in the universe, and they coexist. The Milky Way is just one of various galaxies. It is made up of many stars. The solar system is made up of the sun and the planets revolving around it. This is the difference between the universe, the Milky Way and the solar system.

Constellation is to see space from the earth (but mainly the stars of the Milky Way). In order to record this, the ancient Greeks divided it into 88 regions, which are now called constellations.

All right, give it to me.
