How many circumpolar constellations are there?

Question

How many are there and what are their names?

Answer 1

Depends which latitude you are situated at in which hemisphere,

For most northern hemisphere observers Ursa Major, Ursa Minor, Draco, Cassiopeia, Cepheus are circumpolar (constellations that never set), but this depends on the observer's latitude,

Viewed from the equator, there are no circumpolar constellations.

In the Southern hemisphere, the Large and Small Magellanic Clouds, two satellite galaxies of our Milky Way galaxy, are visible on most clear, moonless nights throughout the year. These "clouds" are circumpolar, appearing to circle the pole throughout the year, As do Crux, the Southern Cross and Centaurus, both circumpolar constellations.

Answer 2

a circumpolar constellation to an observer somewhere on earth is one that never sets. you'd definitely do better with a globe to explain. at the North Pole, practically all the northern hemisphere stars will be visible the entire evening, so every complete constellation you see will be circumpolar. the farther south from the North Pole you stand, the closer the North Star will be to the northern horizon and the greater the number of stars/constellations that will actually rise and set. probably the easiest way would be to take them to a planetarium, though.

Answer 3

Circumpolar means the constellation lies at or near the north or south pole projected onto the sky.
Since the earth has 2 poles (one north and one south), it stands to reason there are 2 circumpolar constellations.
The one around the north pole is Ursa Minor (which contains Polaris, the North Star).
You will have to look up what constellation (if any) contains the South Pole star.

Answer 4

It depends on your latitude. At the equator there are none. At the pole about half of them. There are a total of 88 constellations in the whole sky, but I don't know if they are evenly distributed between the northern and southern hemispheres.
