As the Earth revolves around the Sun during the year, different constellations are visible in the night sky during each season of the year.
A good example is Orion, which is high in the night sky during the winter in the northern hemisphere. During the summer, Orion is still in the sky, but only in the daytime, so we don't see Orion in the summer.
On the other hand, Cygnus and Lyra are examples of prominent constellations visible in the northern hemisphere summer. They are high in the sky during the night all summer.
With each season, different constellations are visible. This pattern repeats year after year, century after century, millennium after millennium.
