The constellations that never set in the sky over the UK are known as circumpolar constellations. These constellations are located close enough to the celestial pole (the point in the sky that the Earth's axis points to) that they appear to circle around it without ever dipping below the horizon.

Here are some of the most prominent circumpolar constellations visible from the UK:

* Ursa Major (The Great Bear): This is the most famous constellation in the Northern Hemisphere. The Big Dipper is a well-known asterism within Ursa Major.

* Ursa Minor (The Little Bear): This constellation contains Polaris, the North Star.

* Draco (The Dragon): This long, winding constellation circles around Ursa Minor.

* Cepheus (The King): Located near Cassiopeia, Cepheus is a less prominent but still recognizable constellation.

* Cassiopeia (The Queen): This constellation is easily recognizable by its distinctive W-shaped pattern.

While these constellations are always visible, their exact position in the sky will change throughout the year. You can use a star chart or a mobile astronomy app to help you identify them.
