Northern circumpolar constellations revolve around the north celestial pole in a counterclockwise manner. They never seem to rise or set, in regards to the horizon. Every 24 hours they seem to complete a revolution around Polaris, the North Star. Because the Earth is a sphere, the number of circumpolar constellations that one sees depends on one's location from the North Pole. At the North Pole, every constellation in the night sky is circumpolar. Below the equator, one cannot see a single circumpolar constellation.
These are the common circumpolar constellations of 40-50 degrees N latitude:
Ursa Major
Ursa Minor
Cassiopeia
Cepheus
Draco
What else can I help you with?
Are there circumpolar constellations on the equator?
No, circumpolar constellations are those that never set below the horizon as viewed from a certain latitude. On the equator, all constellations are visible at some point during the year but none are permanently circumpolar.
Why is the zodiac not circumpolar?
The zodiac is not circumpolar because it lies near the ecliptic, which is the apparent path that the Sun follows in the sky. As a result, the zodiacal constellations are not visible all year round from all latitudes on Earth. This is in contrast to circumpolar constellations, which never set below the horizon.
When circumpolar stars can be seen?
Circumpolar constellations are those that never set below the horizon. The further north (or south) one travels, the more constellations are circumpolar. Where I live, above the 45th parallel, most of the Big Dipper stars are circumpolar, but Arcturus is not, and the constellation of Orion sets below the horizon in the summer. Equatorial constellations are those that pass directly overhead when one is between the tropics of Cancer and Capricorn. I believe these are primarily the 13 constellations of the zodiac.
Where are circumpolar constellations located?
For example, if you live at a latitude of 50° north, the circumpolar stars will be all stars that are up to 50° around the celestial north pole. As another example, if you live at a latitude 30° south of the equator, the circumpolar stars will be all those that are in a circle up to 30° around the celestial south pole.
What characteristic classifies a constellation as circumpolar?
Circumpolar, like beauty, is in the eye of the beholder. Technically, a circumpolar constellation is one that never sets, but just goes around the elevated pole. That's the north star Polaris in the northern hemisphere, or the blank spot of space above the south pole. This, however, depends on your latitude; the higher your latitude, the more constellations are "circumpolar" for you. I live near Sacramento, CA, USA, at latitude about 38 degrees north, so any constellation within 38 degrees of Polaris is "circumpolar" for me. That includes constellations such as Ursa Major, Cassiopeia, and Draco, but not constellations like Orion.
How many constellations are circumpolar?
There's no answer to this question, because the definition of circumpolar depends on where you are. If you're at the pole, all the constellations you can see are circumpolar. If you're on the equator, there are no circumpolar constellations.
Which constellations can be seen all year?
The circumpolar constellations
Are there circumpolar constellations on the equator?
No, circumpolar constellations are those that never set below the horizon as viewed from a certain latitude. On the equator, all constellations are visible at some point during the year but none are permanently circumpolar.
Why aren't all constellations visible all year?
Circumpolar constellations are visible all year long, depending on where you are viewing them from. At the north pole, or the south pole, some constellations are visible year-round, these are the circumpolar constellations. On the equator, there are no circumpolar constellations because of the earths rotation, that is why circumpolar constellations are at the "poles". Some of the circumpolar constellations can also be viewed from other parts of the same hemisphere, such as the big dipper and the little dipper, although they are circumpolar, they are also seen in other parts of the northern hemisphere. Circumpolar constellations in the northern hemisphere, will never be seen at the south pole, and vice versa. I hope this helped.

Is there a place on earth where no constellations are circumpolar?
No, all locations on Earth have constellations that are circumpolar, meaning they never dip below the horizon. The specific constellations will vary depending on the observer's latitude.
Constellations that circle polaris are?
These are called circumpolar constellations.
Is a circumpolar constellation?
No. All circumpolar constellations are found near the celestial poles. Because of their proximity to the poles, they never disappear from view. Sagittarius is on the ecliptic and thus (like all other zodiac constellations) not close enough to the poles to render it circumpolar.
What are constellations that circle polaris called?
These are called circumpolar constellations.
Why does the number of circumpolar constellations depend on latitude?
Circumpolar Constellations are those that appear to circle the North Star, Polaris. Polaris' place in the sky changes based on the viewers latitude. The closer you get to the North Pole, the higher in the sky Polaris appears, and therefore the more constellations appear to spin around Polaris.
What do all constellations have in common?
Northern circumpolar constellations revolve around the north celestial pole in a counterclockwise manner. They never seem to rise or set, in regards to the horizon. Every 24 hours they seem to complete a revolution around Polaris, the North Star.

Which must be true of circumpolar constellations at the South Pole?
Circumpolar constellations are always visible in the night sky from a specific location, such as the South Pole, as they never set below the horizon. At the South Pole, all circumpolar constellations can be seen at some point during the year, as they revolve around the celestial point directly above the Earth's axis.
