It's true that the Earth orbits the Sun, and that's because the Sun has a much larger mass than Earth. That means it has a stronger gravitational pull, and the Earth is pulled into a curved path around it.
But the Sun itself doesn't orbit anything in the same way. It is the center of our solar system, and the other planets, including Earth, orbit around it.
However, the Sun does move. It's actually part of a larger system called the Milky Way galaxy. The Sun and all the stars in our galaxy are orbiting the center of the Milky Way galaxy, which is where a supermassive black hole is located.
So, to summarize:
* The Earth orbits the Sun.
* The Sun orbits the center of the Milky Way galaxy.
