Question

explain why do you see different stars in springs night sky than in falls night sky?

Explanation:

The Earth orbits the Sun. As it moves in its orbit, the part of the universe (and thus the stars) that is visible at night changes. In spring, the Earth is in one part of its orbit, and in fall, it is on the opposite side of the Sun, resulting in different star - fields being visible.

Answer:

The Earth's orbit around the Sun causes the change in the visible stars between spring and fall.
