What constellation are we in?

The Milky Way is the galaxy to which the earth and the sun belong. It is named because the bright band whose main part is projected on the celestial sphere is called the Milky Way in China. There are about 200 billion stars in the Milky Way. The Milky Way looks like a big disk with a slightly protruding center. The diameter of the whole disk is about 654.38+ million light years, and the sun is located 23,000 light years away from the center of the Milky Way. What bulges is a silver heart, which is a dense area of perseverance, so I look at a vast expanse of whiteness. Seen from above, the Milky Way is like a huge whirlpool, consisting of four spiral arms. The solar system is located in one of the spiral arms (Orion arm) and rotates counterclockwise (it takes 250 million years for the sun to rotate around the center of the Milky Way).

Outside the main spiral arm is an outer ring or unicorn ring, which was proposed by astronomers Brian Yanni and Heidi Joe newberg.
