Stars near the north celestial pole and the south celestial pole become "circumpolar" at high latitudes. They "circle around the pole". For example, the star Polaris never sets anywhere in the northern hemisphere. Constellations like the Big Dipper, Draco or Cassiopeia are "circumpolar" north of about 30 degrees north latitude.
While there is no "south pole star", a constellation such as the Southern Cross is circumpolar south of about 40 degrees South.

What is the formula for calculating whether a star is circumpolar viewed from a northerly latitude?
To determine if a star is circumpolar (never sets) when viewed from a northerly latitude, you can use the formula: 90° - latitude + declination >= 0. If the result is greater than or equal to zero, then the star is circumpolar from that latitude. The declination is the star's angular distance north or south of the celestial equator.
What star constellation rises in the east and sets in the west?
All of them - except the ones that are circumpolar (that don't rise or set at all). Which ones are circumpolar depends on your latitude.
A star that is always visible in the night sky is called?
A star that is always visible in the night sky is called a circumpolar star. These stars are located near the celestial pole, allowing them to remain above the horizon throughout the night, regardless of the Earth's rotation. Examples include Polaris in the Northern Hemisphere and Sigma Octantis in the Southern Hemisphere.
How can you determine your latitude in the northern hemisphere just by using a star?
To determine your latitude in the northern hemisphere using a star, measure the angle between the horizon and the star using a sextant. This angle is called the star's altitude. If you know the star's declination (which is constant), subtract it from 90 degrees minus the star's altitude to find your latitude.
The two sets of lines the geographic grids consist of?
Longitude and latitude.
What day does the star Aldebaran set at 1100 pm?
The answer depends on where you are. For a places further north than 73½º north Aldebaran never sets at all. Alternatively for places further south of 73½º south it never rises. In between, it depends on the latitude.
What never sets at your latitude?
Any sky object within (your latitude) degrees of the north celestial pole.

To determine if a star is circumpolar (never sets) when viewed from a northerly latitude, you can use the formula: 90° - latitude + declination >= 0. If the result is greater than or equal to zero, then the star is circumpolar from that latitude. The declination is the star's angular distance north or south of the celestial equator.
What time does the star Arcturus rise on February 10?
The answer depends on where you are. Arcturus has a declination of 19¼ degrees north, which means it passes overhead at all places with a latitude of 19¼ degrees north. For a places further north than 70¾º north Arcturus never sets at all. Alternatively for places south of 70¾º south it never rises. In between, it depends on the latitude.
What star constellation rises in the east and sets in the west?
All of them - except the ones that are circumpolar (that don't rise or set at all). Which ones are circumpolar depends on your latitude.
What object with what declination would be above the horizon for the longest amount of time at your location?
Any star whose declination is higher than (90 - your latitude) will be "circum-polar", meaning that the star will never appear to set. The star Alkaid, one of the handle stars in the Big Dipper, has a declination of 49 degrees. If your latitude is 90-49=41 N, then the star Alkaid will never go below the horizon.
A star that is always visible in the night sky is called?

These stars are located near the celestial pole, allowing them to remain above the horizon throughout the night, regardless of the Earth's rotation. Examples include Polaris in the Northern Hemisphere and Sigma Octantis in the Southern Hemisphere.
How can you determine if a star is circumpolar from a certain latitude?
All stars are circumpolar, but the term has come to be applied to those starsthat never set, as seen from a given latitude.Any star that's within (your latitude) of the celestial pole doesn't set, as seenfrom your latitude.If you're working from a celestial almanac, look for stars for which(star's declination) plus (your latitude) is greater than 90° .
How the latitude of an observer may be determined by observation of the pole star?
The angle between the Pole Star and the horizon is equal to your latitude.
What star helps people navigate in the northern hemisphere?
Polaris, the 'North Star', which never sets, and indicates the direction of north. Polaris is the last star in the handle of the Little Dipper, Ursa Minor. ('Little Bear,')
How can you determine your latitude in the northern hemisphere just by using a star?
