That depends on the latitude from which you are observing Polaris.
At the Equator (0 latitude) Polaris will be tangential to the northern horizon (0 degrees of altitude)
At 52 degrees north the altitude of Polaris will be 52 degrees
Therefore At the North Pole (90 latitude) Polaris will be overhead (90 degrees of altitude).
That depends on the time of day and on your latitude. At the Winter Solstice (about December 21 in the northern hemisphere, or June 21 in the Southern Hemisphere) the Sun will be at 90-<Your Latitude>-23.5 degrees above the horizon at local apparent noon.
So here in Sacramento, CA, USA where I live, on December 21 at noon, the Sun will be 90 - 38.5 - 23.5 = 28 degrees above the southern horizon. No wonder it feels so cold!
"Altitude". This varies moment to moment and depends on the precise time and your position on the Earth. A precise altitude measurement of three stars is enough to calculate your location quite accurately; this is called "celestial navigation", and is easy enough to learn. (I used to teach it.)
The word "zenith" means "the highest", and it is the point that is straight up. The angle of altitude for the zenith is always 90 degrees.
All the way round there are 360 degrees, which was decided by the early astronomers in Babylon in about 700 BC.
"At zenith" means directly above your head - so high that it can't go any higher.
90.
There are many things that horizon A and horizon B could form. These things include slopes and lines for example.
A horizon and one can be seen from every point on Earth.
If you are talking about the geographic idea of horizon, there are infinitely many. Horizon is not a thing or a place, but a relationship between an observer and the thing observed, usually a planet or moon.
20 degrees celsius is not too hot or not too cold. It is moderate weather. Almost the equivalent to 70 degrees fahrenheit. Here is a typical scale 0-10 degrees celsius is cold weather 11-29 moderate weather 30 and above is hot weather
Room temperature may be 20 degrees Celsius that is equal to 68 degrees Fahrenheit. There is no fixed room temperature. I feel a bit chilly at 68 F (20 C) in the winter time and warm at 75 F (22 C) in the summer. Most people are comfortable at temperatures in this range.
On the winter solstice at a latitude of 57 degrees north, the sun will be about 33 degrees below the horizon at night. This is because the tilt of the Earth causes the sun to not rise above a certain angle during the winter months at this latitude.
Seattle's latitude is about 47.6 degrees North. So the altitude of Polaris above the northern horizon is always within about 1/3 degree of that angle as seen from there.
It depends on the time of night and day - it circles the North Star constantly. The North Star is 34 degrees above the horizon - it stays in the same spot all the time (just about).
The altitude of the highest point of the rainbow that you see is (42 degrees) minus (the altitude of the sun above the horizon behind you). If the sun is sitting right on the horizon ... just risen or just about to set ... then the highest point of the rainbow is about 42 degrees above the horizon opposite the sun. If the sun is higher, then the rainbow is lower, by the same amount. If the sun is more than about 42 degrees above the horizon, then any rainbow you might otherwise see is entirely below the opposite horizon, and you don't see one.
That depends on the exact moment of the day (between the time you write the question and I answer, the Moon may already have moved ahead quite a bit), and on where exactly you live. In other words, the Moon can be anywhere between 90 degrees above and 90 degrees below the horizon, depending on the above-mentioned circumstances.
It can be just about any height. To get a specific answer, you would also have to know how high the Sun is in the sky - how many degrees above the horizon; and that can be anythiing between 0 and 90 degrees.
In summer it hovers just above zero. In winter it can drop to 40 degrees below zero. In terms of Latitude, the arctic is the region above the arctic is the region north of 77 degrees north
None. The closest it gets is on December 21, when the sun climbs to a dazzling 43 degrees above the northern horizon.
At the equator, the celestial north pole would be north, just at the horizon. In the southern hemisphere, for instance in Australia, the north celestial pole would be north, and as many degrees BELOW the horizon as your latitude. For instance, if you are 10 degrees south of the equator, the celestial north pole would be 10 degrees below the equator.On the other hand, for people in the southern hemisphere, the celestial SOUTH pole would be ABOVE the horizon; this same pole is below the horizon for anybody in the northern hemisphere.
The altitude doesn't depend much on whether the night is clear.If you live in the northern hemisphere, the altitude of Polaris above the horizon will APPROXIMATELY be equal to your latitude. If you live in the southern hemisphere, Polaris will be BELOW the horizon, as many degrees as you are south of the equator.
The answer depends upon how far north (or south) you are. During the winter solstice at the north pole (or anywhere above the arctic circle), there is no sunlight whatsoever. The further south you go, the longer the sun peeps up above the southern horizon at noon.
37 degrees north latitude
