How does the rotation speed of stars in the Milky Way disk vary with distance from the center?
Answer
Stars farther out take longer to complete an orbit
The material in the Milky Way disk rotates, but not as a solid body; stars positioned farther out from the galactic center require a longer duration to complete a full orbit.
