Circumpolar stars always reside above the horizon, and for that reason, never rise nor set. All the stars at the Earth’s North Pole and South Pole are circumpolar. Meanwhile, no star is circumpolar at the equator.
Which constellations are circumpolar?
Circumpolar constellations seen from the northern hemisphere
Ursa Major. You might not be aware of it, but circumpolar constellations are some of the most well known groups of stars in the sky. The Ursa Minor, also called the Little Dipper, is another circumpolar constellation which never sets in the northern sky. Cassiopeia is a northern circumpolar constellation with a very discernible shape, that can be viewed all year long. As we’ve seen with other constellations, the story behind the Cepheus constellation is also linked to its neighboring patterns of stars. Draco is a circumpolar constellation only present in the northern hemisphere. This means that Draco is never visible for those living in the southern hemisphere.
The three southern circumpolar constellations visible from most locations in the southern hemisphere are Carina, Centaurus, and Crux. Other constellations are just as prominent in the sky and can be seen for most of the year, but only these eight are circumpolar.
Why are there no circumpolar constellations in North America?
The same goes for the southern constellations: their stars never rise or set, but only rotate around the pole. For observers in equatorial latitudes, there are no circumpolar constellations as the stars change from season to season.

What are the northern circumpolar constellations?
Northern circumpolar constellations. The constellations Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor are found circling Polaris, the North Star, located in Ursa Minor. Three of these constellations are very easy to find in the night sky because they are dominated by familiar asterisms, formed by their brightest stars.
You could be asking “Which constellation does not set in the northern sky?”
The Ursa Minor, also called the Little Dipper, is another circumpolar constellation which never sets in the northern sky. The greatest particularity of Ursa Minor is the last star found in its tail. This star is known as Polaris, or the North Star, and it never moves from its spot in the northern night sky.
You may be thinking “How many constellations are there in the northern hemisphere?”
The five northern constellations visible from most locations north of the equator throughout the year are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor. The three southern circumpolar constellations visible from most locations in the southern hemisphere are Carina, Centaurus,.
Do circumpolar stars rise and set?
Circumpolar stars neither rise nor set, but stay up at all hours of the day, every day of the year. Even when you can’t see them – when the sun is out and it’s daytime – these stars are up there, circling endlessly around the sky’s north or south celestial pole.
At the Earth’s equator, no star is circumpolar because all the stars rise and set daily in that part of the world. You can (theoretically) see every star in the night sky over the course of one year. In practice, of course, things like clouds and horizon haze get in the way.
What constellations are found at the celestial poles?
All circumpolar constellations are found near the celestial poles and, due to their proximity to the poles, they never disappear from view. The five northern constellations visible from most locations north of the equator throughout the year are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.
Constellations in the northern circumpolar sky include Auriga, Camelopardalis, Cassiopeia, Cepheus, Draco, Lynx, Perseus, Ursa Major, and Ursa Minor. These constellations are always visible in the night sky of the Northern Hemisphere. Constellations in the southern circumpolar sky include Grus, Phoenix,.
What constellations circle around Polaris?
The Polaris, the North Star, is actually a part of the Ursa Minor constellation, and as we’ve discussed the Ursa Major, Ursa Minor, Cassiopeia, Cepheus and Draco constellations can always be seen as circling the Polaris year-round if you are located in the Northern Hemisphere.
