Which constellation does the solar system revolve around?

The solar system is located in a galaxy called the Milky Way (a rod-like galaxy with a diameter of 100000 light-years and about 200 billion stars). Our sun lies on a spiral arm outside the Milky Way, which is called Orion arm or Ben spiral arm. The sun is 25,000 to 28,000 light years away from the center of the Milky Way, and its speed in the Milky Way is about 220km/s, so it takes 225m to 250m years to circle the Milky Way. This period of revolution is called the year of galaxies. ?

The location of the solar system is the scattered stars in the Milky Way, which are called local interstellar clouds. This is an interstellar medium, shaped like an hourglass, with dense gas and few stars, with a diameter of about 300 light years. It is called a local galaxy bubble.

At present, the Milky Way, where the solar system is located, is in an orbit that collides with the Andromeda Nebula. It is expected that contact will begin in 2 billion years. Our solar system is now about 30,000 light-years away from the silver core? By then, the solar system will be pushed by the Andromeda Nebula to a distance of 65438+ million light years from the silver core.
