Can't leave the Milky Way? We need 17600 years to fly out of the solar system

The Milky Way is a cluster formed by the aggregation of stars, with the main members being stars. The Milky Way belongs to the barred spiral galaxy, with spiral arms mainly composed of gas, dust, and stars extending from both ends of the central nucleus. Stars are mainly clustered on the two spiral arms, while the other two are not yet fully formed. The solar system is located on the Orion arm of the Milky Way, where stars gather.

　　
After discussing the Milky Way, let's take a look at the structure of the solar system. As a star system, the solar system is mainly centered around the Sun, followed by the eight major planets, with the asteroid belt interspersed among them.

　　
The outer layer is the Kuiper Belt, mainly composed of dwarf planets, asteroids, and other celestial debris. There is a hypothetical spatial structure in the outer layer of the Kuiper Belt called the Oort Cloud. The Oort Cloud is believed to be the home of long-period comets, where there is a large amount of celestial debris from the early stages of the formation of the solar system.
The diameter of the Oort Cloud is approximately 2 light-years, which is the range of the solar system determined by the gravitational force of the sun.
