Some constellation such as Ursa Minor are visible in the sky year-round other constellations appear for only part of the year?

Ursa Minor, along with other circumpolar constellations, is visible year-round due to its position near the North Celestial Pole, allowing it to remain above the horizon throughout the year. In contrast, many constellations are seasonal; their visibility changes with the Earth's orbit around the Sun, causing them to rise and set at different times of the year. This means that some constellations may only be seen during specific seasons, depending on the observer's location. This cyclical visibility is influenced by the tilt of the Earth's axis and its orbital path.
