The universe is not moving around the Earth once per day. The Earth rotates counterclockwise in this diagram, carrying observers with it. The positions where observers on the equator are experiencing sunrise, noon, sunset, and midnight are marked. Note that half of the entire celestial sphere is always above your horizon plane. The horizon plane sweeps across sky as Earth spins and determines the rising and setting of objects.
Objects rise over the eastern horizon and set toward the western horizon.
By combining the concept of the horizon plane with the definition of local time in the left-hand panel, you can visualize what parts of the sky are observable at any given time . Seen face-on, the orbit is technically an ellipse but deviates only slightly from a circle. Seen edge-on, the orbit is a thin line. See figures above. The night side of Earth is that opposite the Sun.
