Final answer:
The Sun is moving through space and orbits the center of the Milky Way galaxy. It moves in the disk plane and is also moving outward away from the center of the galaxy.
Step-by-step explanation:
The Sun is moving through space. It is not stationary or fixed in one position. The Sun, along with the rest of the solar system, orbits the center of the Milky Way galaxy. This movement is called galactic rotation or orbital motion.
As the Sun orbits the center of the galaxy, it is moving in a path called the disk plane. This disk plane is the flattened region of the galaxy where most of the stars and other celestial bodies are located. The Sun is also moving outward away from the center of the galaxy, towards the outskirts of the Milky Way.
