The Milky Way is a oblate sphere with a huge disk structure, consisting of a bright and dense core, two main spiral arms and two unformed spiral arms, which are 4,500 light years apart. The sun is located on the arm of Orion, an arm of the Milky Way, and the distance to the center of the Milky Way is about 26,000 light years.

Our solar system is located at the edge of the Milky Way, about 30,000 to 50,000 light years away from the center of the Milky Way. Scientists believe that there is a black hole in the center of the Milky Way, which attracts many galaxies and moves in a circle around itself. Because no one knows how big the universe is now, and human beings don't know their position in the universe, but what is certain in the galaxy is that human beings are not the center of the galaxy, and the earth is on the edge of the galaxy. Scientists say that with the earth as the center and a radius of several light years, only the earth is known to have life.
