21. Is the Sun moving in space? (A K2S Question)

From The Space Library

Yes, everything is moving in space. Just as the Earth has a yearly orbit around the Sun, our Sun also orbits the center of our Milky Way Galaxy once every 230 million years. It is amazing to think about the fact that the last time our Sun passed through this area of the Milky Way Galaxy was when the dinosaurs were still alive on Earth! All the solar system orbital motion is a consequence of the motion of the original cloud of gas that formed in this region of space and eventually gravitationally collapsed to form the Sun and all the planets, comets and asteroids in our solar system.
