They are always visible in the sky. (Unless it's cloudy).
They don't "rise" and "set" at the latitudes where they are circumpolar.
At the equator, you will see no circumpolar stars.
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.
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 they do not. By definition circumpolar stars do not "rise". They are above the observer's horizon at all times.
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.
Circumpolar stars are stars that never dip below the horizon for an observer at a certain latitude, making them visible year-round. They appear to rotate around the celestial pole without setting, unlike other stars that rise and set each day. This unique characteristic makes them useful for navigation and timekeeping.
During roughly half of the time, 'circumpolar' stars don't appear to move from east to west. Which ones those are depends on your latitude. All other stars all the time, and circumpolar stars for the other half of the time, do appear to move from east to west.
No. The Zodiac are 12 constellations that lie in the plane of the ecliptic; circumpolar ("moving around the pole") stars are well above or below the ecliptic.
A circumpolar star is a star that, due to its position relative to the Earth's celestial poles, never sets below the horizon for observers at certain latitudes. In the Northern Hemisphere, stars like Polaris remain visible all night throughout the year, while in the Southern Hemisphere, stars such as Alpha Centauri can be circumpolar. The exact stars that are circumpolar depend on the observer's latitude; the closer one is to the poles, the more stars can be seen as circumpolar.
Stars located near the Earth's poles that can be seen year-round at all times of night are called circumpolar stars. These stars appear to rotate around the pole and do not rise or set like other stars in the sky due to the Earth's rotation.
From the northern hemisphere, circumpolar stars appear to be circling around the North Star, also known as Polaris. This is because the North Star is located near the North Celestial Pole, making it a fixed point in the sky around which the circumpolar stars appear to revolve.
For example, if you live at a latitude of 50° north, the circumpolar stars will be all stars that are up to 50° around the celestial north pole. As another example, if you live at a latitude 30° south of the equator, the circumpolar stars will be all those that are in a circle up to 30° around the celestial south pole.
