If you were standing on the equator, how many circumpolar stars would you see?
At the equator, you will see no circumpolar stars.
To calculate the range of declinations for which stars are circumpolar, you need to know the observer's latitude. Circumpolar stars are those that never set below the horizon. For a given latitude ( \phi ), the declination (( \delta )) of circumpolar stars ranges from ( +90^\circ - \phi ) to ( -90^\circ + \phi ). Thus, if you are at a latitude of, say, 40°N, circumpolar stars would have declinations between ( +50^\circ ) and ( -50^\circ ).
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.
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.
On June 21 at the Equator, the sun would rise directly east. Regardless of where you are on the Equator, the sun would rise due east and set due west.
At the equator, you will see no circumpolar stars.
If you were standing on the North Pole, you would be able to see all the circumpolar stars in the sky. Circumpolar stars are the stars that never set and orbit around the celestial pole. At the North Pole, they would constantly circle around Polaris, the North Star, without dipping below the horizon.
Nothing seen in the sky from a point on the Equator is "circumpolar", meaning that everything in the sky appears to rise and set.

At the North Pole, and at the South Pole.
Subtract your latitude from 90° and that will give the the decollation of circumpolar stars. In northern New Zealand, my latitude is 35°. If I subtract that from 90°, I get 55°. So stars with Declination great than 55° are circumpolar for me.
They believed that when Paraohs died they would become one of the circumpolar stars
The region of the sky visible all year round is called "circumpolar". What stars and constellations are included there depends on your geographical location. For example, for somebody living 30 degrees south of the equator, a region around the south pole of the sky, with a radius of 30 degrees, would be circumpolar.
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.

gemini is not circumpolar. the circumpolar constellations for the northern hemisphere are Cassiopeia. Ursa Minor, Draco, Cepheus, and Ursa Major.
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.
