This analogy best describes the shape of how the stars located in the galactic disk orbit.

Explanation:

According to many recent scientific studies, it is estimated that our Milky Way has over 200 billion stars, in which most of all are located in the Galactic disk, close to the nucleus and bulge in the center.

The galactic disk is made of a large quantity and percentage of gas and dust as well a huge number of stars, both old and young ones. In this faction of the milky way, the galactic center is orbited by the stars in circular motions, which is due to the interaction with gravity causing some up and down actions mixed with the circular orbits.
