How does the heliocentric model of planetary motion explain a star’s path across the night sky?
How does the heliocentric model of planetary motion explain a star’s path across the night sky? Earth moves along its orbit daily to follow the stars. The rotation of Earth makes objects in the sky appear to move. Each star creates a different amount of light, imitating movement.
