The seasonal appearance of stars is influenced by Earth's orbit around the Sun. In summer, observers face a different direction in space at night than in winter due to Earth's orbital position [1]. Summer constellations are visible because they are on the side of the Sun facing Earth, while in winter, these constellations are not visible as they are on the Sun-facing side away from Earth [2]. The Earth's position affects the orientation of the night sky, revealing different constellations in different seasons [7].
