Schematic diagram of the sun's orbit

Let's describe it. It is difficult to draw a picture.

The sun's orbit revolves around the center of the Milky Way, roughly in a plane, and may fluctuate.

Because the structure of the Milky Way is much more complicated than that of the solar system, all the stars revolve differently from the planets in the solar system. Moreover, the revolution of a star is not just an absolutely large particle around the center of the Milky Way, but the center of gravity formed around the annular plane of the star. The center of gravity of the ring formation will change somewhat, unlike the center of gravity of the solar system is the sun.

In addition, the stars in the Milky Way are rigid when they run around the center of the Milky Way, that is, the stars near the center of the Milky Way are slow, the stars far away from the center of the Milky Way are fast, and the stars too far away from the center of the Milky Way will slow down. In the solar system, planets close to the sun rotate faster, while planets far from the sun rotate slower.
