Yes, it is nearly circular in orbit. However, the stars outside the "disk" rotate in a much more complicated way.
Yes, our solar system does move within the Milky Way galaxy. In fact, it is constantly in motion. The Milky Way galaxy is a large spiral galaxy, and our solar system is located about two-thirds of the way from the center of the galaxy to the outer edge, in the Orion Arm.
To understand how our solar system moves within the Milky Way, we need to consider two aspects: rotation and revolution.
1. Rotation: The Milky Way galaxy rotates around its center, like a spinning disc. This means that all the stars, including our Sun, also move in a circular path around the galactic center. It takes about 225-250 million years for our solar system to complete one full rotation around the galaxy.
2. Revolution: In addition to rotating, our solar system is also traveling through space as the Milky Way itself moves. The whole galaxy is moving in relation to other galaxies under the influence of gravity. Our solar system, along with the rest of the stars in the Milky Way, is moving towards the general direction of the constellation of Leo at a speed of about 230 km/s (143 miles/s).
So, the answer is yes, our solar system is constantly in motion as it rotates around the center of the Milky Way galaxy and moves within the galaxy itself.
