What do all circumpolar 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. 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
Why do stars and constellations also appear to rise and set?
Stars and constellations appear to rise and set due to the rotation of the Earth on its axis. As the Earth rotates, different stars and constellations come into view or move out of view from a specific location on Earth, giving the illusion of them rising and setting.
In the northern hemisphere there are some stars that do not appear to rise or set as other stars do These stars are?
Circumpolar stars. In the northern hemisphere, the north star does not rise or set; the north pole is always pointing toward it. The canopy of stars moves around the north star over the course of a day, giving the apparent rising in the east and setting in the west of most stars as the canopy dips below and moves above the horizon. The stars that are close enough to the north star never set. The part of the canopy that is visible at night changes over the course of a year.
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.
The parallel ring of latitude where the sun does not set on the day of the summer solstice and does not rise on the day of the winter silstice it is near the north pole?
There is one of these 'rings' around the north pole ... called the Arctic Circle ... and another one around the south pole ... called the Antarctic Circle. These circles mark the farthest distance from each pole that can possibly have 24 hours without a sunrise, and 24 hours without a sunset. Each of them is located 23.5 degrees (of latitude) away from its pole. On June 21, the sun doesn't set on the Arctic Circle (the north one), and doesn't rise on the Antarctic Circle (the south one). On December 21, there's no sunrise on the Arctic Circle, and no sunset on the Antarctic Circle.
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.

Why does the number of circumpolar constellations depend on the latitude of the observer?
As an observer moves away from the equator, towards the north or south pole, there are more constellations that the rotation of the earth does not ever block from his or her view throughout one full rotation.
Which constellations never set in the sky over the UK?
The circumpolar constellations, such as Ursa Major (containing the Big Dipper), Cassiopeia, and Draco, never set in the sky over the UK. These constellations are located near the North Celestial Pole, so they appear to constantly circle around the pole without ever disappearing below the horizon.

Circumpolar constellations orbit what?
Beautiful question !! Circumpolar stars and constellations are stars and constellations the "go around the pole" = Circum (circle) polar (the pole) The North Star is called "Polaris" because it's directly above Earth's North Pole - in other words, if you went to the North Pole, "polaris" would be directly over your head. Because of this, all of the stars appear to pivot around Polaris as Earth rotates. Now I don't know where you live, but if you live in the United States, Polaris would NOT be overhead - it would be lower in the sky but still in the North. The lower on the globe you live, the lower Polaris appears in the sky. So, the stars and constellations that spin around Polaris but DON'T SET, are called circumpolar stars and constellations.
How do fishermen use constellations?
The constellation Ursa Minor, the little bear, contains the star Polaris which, in modern times appears to remain stationary above the North Pole. This can help people in the Northern hemisphere locate the northward direction.There are other constellations which rise and set at different times of the night in different seasons. This information can be ueful in telling the time.

Do stars constellations also appear to rise and set?
Every natural object in the sky appears to rise in the east and set in the west.
Where on Earth so stars always circle the zenith and never rise and set?
The stars always circle the zenith, or the point directly overhead, at the North Pole. This phenomenon occurs due to the Earth's rotation on its axis, which causes the stars to appear to move in a circular pattern above the North Pole without rising or setting.
How many hours are in a day at the North pole?
A day is still 24 hours. The sun may not rise or set during that period.
