- Ursa Major (the Big Dipper or the Great Bear)
- Cassiopeia (the Lady in the Chair – the constellation shaped like a “M”
- Cepheus (the King)

Are more stars circumpolar at the North Pole?
So as you go farther north, more stars are circumpolar. And if you go all the way north — to the north pole — all the stars are circumpolar — nothing ever rises or sets. Instead, each star follows the same path across the sky night after night, circling the hub of the northern sky: Polaris.
Why are there more circumpolar stars at the North Pole?
Circumpolar stars always reside above the horizon, and for that reason, never rise or set. All the stars at the Earth’s North and South Poles are circumpolar. The closer you are to either the North or South Pole, the greater the circle of circumpolar stars, and the closer you are to the equator, the smaller.
How many circumpolar stars can you see from the North Pole?
At the equator no star is circumpolar. At the North or South Pole all stars that are visible at all are circumpolar, since only one half of the celestial sphere can ever be seen.
What are the 5 northern circumpolar constellations?
The main circumpolar constellations are Ursa Major, the Great Bear; Ursa Minor, the Little Bear; Draco, the Dragon; Cepheus, the King; and Cassiopeia, the Queen. The circumpolar constellations travel in circles around the North Star, Polaris.
How many circumpolar stars are there?
There are 9 constellations that are circumpolar in the Northern Hemisphere, Auriga, Camelopardalis, Cassiopeia, Cepheus, Draco, Lynx, Perseus, Ursa Major, and Ursa Minor.
Why are there circumpolar stars?
Circumpolar stars exist because of the way the Earth rotates. As the Earth moves around its axis, it follows a circular path around one of the poles. Depending on how close you are to either pole, these stars may appear to move in small circular paths or not move at all.
What are the 5 circumpolar constellations?
At mid-northern latitudes (40º to 50º North) the circumpolar constellations are:
- Ursa Major (The Great Bear)
- Ursa Minor (The Lesser Bear)
- Draco (The Dragon)
- Cepheus (The King)
- Cassiopeia (The Queen)
- Camelopardalis (The Giraffe)
What direction do circumpolar stars move?
For an observer on Earth, circumpolar stars trail in a counterclockwise direction around the north celestial pole but move clockwise about the south celestial pole. Because they’re so positioned, they’re visible all night long and in fact all year long.
Where can you see circumpolar stars?
At the Earth’s North and South Poles, every visible star is circumpolar. That is, at Earth’s North Pole, every star north of the celestial equator is circumpolar, while every star south of the celestial equator stays below the horizon.
Is Cassiopeia circumpolar?
Where do circumpolar stars appear in the sky?
How many circumpolar stars appear in your sky depends on where you are. At the Earth’s North and South Poles, every visible star is circumpolar. That is, at Earth’s North Pole, every star north of the celestial equator is circumpolar, while every star south of the celestial equator stays below the horizon.
Is the north pole directly overhead or circumpolar?
At the Earth’s North Pole, the north celestial pole is directly overhead, and all stars that are visible at all (that is, all stars in the Northern Celestial Hemisphere) are circumpolar.
Are there any circumpolar constellations at the North Pole?
At its extreme, every northern hemisphere constellation is circumpolar at the north pole because the NCP is overhead. There are five constellations which are circumpolar in all states except Florida and Hawaii: Further north there are more circumpolar constellations.
Is the Southern Cross a circumpolar star?
The Southern Cross is circumpolar anywhere south of 35 degrees south latitude; yet, in the Northern Hemisphere, it’s the W or M-shaped constellation Cassiopeia that’s circumpolar at all places north of 35 degrees north latitude. (Scroll upward to the chart showing Cassiopeia at nightfall for mid-northern latitudes.)
