Why are there different constellations visible at different times of the year?

Different constellations are visible at different times of the year due to the Earth's orbit around the Sun. As the Earth moves along its orbital path, the night sky shifts, allowing us to see different groups of stars at different times. This change is also influenced by the tilt of the Earth's axis, which affects the angle at which we view the stars. Consequently, some constellations become prominent in the night sky during certain seasons while others disappear from view.
