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.

∙ 7y agoThat depends on your latitude. For example, if you live 30 degrees south of the equator, any star that is up to 30 degrees from the south pole of the sky will be circumpolar. In this example, that would be a declination of (90 - 30) = 60 or more. This is a bit theoretical; note that stars that are above the horizon, but very close to it, are hard to see. So, in the above example, a star that has a declination of 62 would never come more than 2 degrees above the horizon; in theory it is circumpolar, but if it is a faint star, you may not be able to actually see it when it is at its lowest position.

When will a star with a right ascension of 2.0 hours rise?
That depends on the date, since the sun itself moves through the entire range of RA during the year. It also depends on the star's declination. Viewed from the northern hemisphere, for example, the greater a star's declination, the earlier it rises, and if its declination is greater than the complement of the observer's latitude, then it never sets.
What is the relationship between the time of year and the angle of the sun in the sky?
The angle of the Sun in the sky, its maximum height above the horizon, depends on a measurement called its declination, which varies over a range of ±23.5 degrees. The Sun's declination is zero at the equinoxes, and is +23.5 degrees at the summer solstice (in the northern hemisphere), the longest day, and -23.5 degrees at the winter solstice, the shortest day. Declination is the Sun's latitude on the celestial sphere, and the declination of any obect is equal to the latitude of a set of points along a line of latitude on the Earth's surface at which it passes overhead.
What is the temperature range highs and lows on mars?
the answer is 31.66 because it has the mass of 34.23 that makes the temp range highs and lows 31.66 please use this answer cause it right!!! thnx
What quality makes earth particulary well- suited to support life?

Where does the snowy owl come from?
The range of the Snowy Owl Nyctea scandiaca is circumpolar - arctic regions of new and old world.

How many degrees longitude is Cassiopeia?
The system of longitude and latitude is designed and used for the purpose of locating points on the surface of the Earth. These coordinates don't refer to celestial (sky) objects. There's a whole separate coordinate system applied to the sky, and there's no constant relationship between that one and the surface coordinates. In celestial coordinates, Cassiopeia occupies the range of Right Ascension between about 22Hr 57Min and 3Hr 37Min, and the range of declination between about 40.7° and 77.55°. Where those coordinates appear in your sky depends on the date and your location.
What makes use of a range?
you cook food on a range and you have a better chance of cooking not burning on a range too. not like logs
In which part of the sky do you see the moon?
The moon's axis is inclined at 5 degrees to the ecliptic, which is inclined at 23.4 degrees to the plane of the Equator. That means that the Moon is seen at any declination in the range ±28.4 degrees. It can be overhead at any latitude between 28.4 degrees north and south. Because of this the Moon can appear further north or south than the Sun and it sometimes appears unusually high or low in the sky.
