How many circumpolar stars would you see if standing on the equator?
Standing on the equator, you would not see any circumpolar stars. Circumpolar stars are those that never dip below the horizon, and they can only be seen from latitudes above a certain threshold, typically around 25 degrees (North or South) or higher. The closer you are to the poles, the more circumpolar stars you can see.
How do you calculate the range of declinations for which stars are circumpolar?
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 ).
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.
Is Orion a circumpolar?
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 rises in the east and sets in the west for an observer in New York?
Most natural celestial objects do this; exceptions would be any fixed star that is 'circumpolar'-- they are close enough to the celestial poles that they never appear to dip below the observer's horizon. Which stars are circumpolar depends on the latitude of the observer.
How many circumpolar stars would you see if standing on the equator?
Standing on the equator, you would not see any circumpolar stars. Circumpolar stars are those that never dip below the horizon, and they can only be seen from latitudes above a certain threshold, typically around 25 degrees (North or South) or higher. The closer you are to the poles, the more circumpolar stars you can see.
If you were standing on the north pole how many circumpolar stars would you see?
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.
How do you calculate the range of declinations for which stars are circumpolar?
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.

Where would you see the most circumpolar stars?
At the North Pole, and at the South Pole.
Where would you be if you couldn't see any circumpolar stars?
Nothing seen in the sky from a point on the Equator is "circumpolar", meaning that everything in the sky appears to rise and set.
What did ancient egyptians believe about astronomy?
They believed that when Paraohs died they would become one of the circumpolar stars
What range of declination makes stars appear circumpolar?
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.
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.
Is Gemini ever circumpolar If so then at what latitude and compass direction would Gemini be a circumpolar constellation?
gemini is not circumpolar. the circumpolar constellations for the northern hemisphere are Cassiopeia. Ursa Minor, Draco, Cepheus, and Ursa Major.

What is the radius in degrees of your circumpolar region be for Dallas Texas?
For Dallas, Texas, the circumpolar region extends approximately 23.5 degrees north and south of the North Pole due to the tilt of the Earth's axis. This means that the circumpolar region for Dallas would be roughly from 23.5 degrees north latitude to the North Pole, encompassing the area where stars appear to move in circles around the North Star, Polaris. Since Dallas is located at about 32.8 degrees north latitude, it does not lie within the circumpolar region.
