The apparent change in constellations with the seasons is a result of the Earth's orbit around the Sun. As the Earth moves through its orbit, different parts of the sky become visible from Earth. This is because the Earth's axis of rotation is tilted with respect to its orbital plane. As the Earth orbits the Sun, this tilt causes the direction in which the Earth is pointing to change. As a result, different parts of the sky become visible at different times of the year.

For example, during the winter in the Northern Hemisphere, the Earth is tilted towards the Sun so that the North Pole is pointing towards the Sun. This means that the stars that are visible from the Northern Hemisphere during the winter are the stars that are located in the northern part of the sky. In contrast, during the summer in the Northern Hemisphere, the Earth is tilted away from the Sun so that the North Pole is pointing away from the Sun. This means that the stars that are visible from the Northern Hemisphere during the summer are the stars that are located in the southern part of the sky.

The change in constellations with the seasons is a natural phenomenon that has been observed by humans for thousands of years. It is a reminder that the Earth is in constant motion and that our view of the sky is always changing.
