Answer:
This is because Earth revolves around the Sun. The constellations in the winter are different from those in the summer. For example, Orion is high up in the evening sky from January to March in winters of the northern hemisphere and summer of the southern hemisphere. In the summer, it's only up in the early morning.However, even today, astronomers at all levels use some of the star patterns that were identified by the ancients; they provide a way to "map" the sky into regions.The patterns of stars rotate as the Sun moves around Earth. As the Earth revolves around the Sun, the patterns of the stars appear to move. As the Earth rotates on its axis, the patterns of stars in the night sky appear to move.The patterns of stars seen in the sky are usually called constellations, although more acurately, a group of stars that forms a pattern in the sky is called an asterism.
