The number of degrees of arc that Polaris is above the horizon depends on what?
Your latitude!
What is the altitude of polaris above the horizon at the tropic of cancer?
Polaris will be 23.5 degrees above the northern horizon when viewed from the Tropic of Cancer.
Where would someone see Polaris if they were at horizon?
If someone is at the horizon, they would see Polaris, also known as the North Star, located at a specific angle above the horizon depending on their latitude. In the Northern Hemisphere, Polaris is positioned nearly directly above the North Pole, so it appears higher in the sky the further north one travels. At the equator, Polaris would be right at the horizon, while in the Southern Hemisphere, it would not be visible at all.
If you measure polaris at an altitude of 60 degrees where are you on earth?
If Polaris appears 60° above the northern horizon, then you are pretty near 60° north latitude. If you're on the equator ... 0° north latitude ... then Polaris is on the horizon ... 0° altitude. If you're at the north pole ... 90° north latitude ... then Polaris is over your head ... 90° altitude. The altitude above the northern horizon at which Polaris appears is nearly identical to your north latitude. ================================================= The difference (error) between Polaris and the real North Celestial Pole is about 0.7 degree. Not good enough for precise navigation or surveying, but just fine for directions when you're hiking.
To an observer on a ship at sea at which latitude does north star appear closest to the horizon?
The North Star (Polaris) appears closest to the horizon at the Earth's equator (0° latitude) because as you move away from the equator towards the poles, the angle of Polaris above the horizon increases. At the North Pole (90° latitude), Polaris is directly overhead.
How do you determine altitude of Polaris?
To determine the altitude of Polaris, you can measure the angle between the horizon and Polaris using a simple instrument like a protractor or sextant. The altitude of Polaris above the horizon corresponds closely to your latitude in the Northern Hemisphere; for example, if you measure Polaris at an angle of 40 degrees above the horizon, you are approximately at 40° latitude. This relationship occurs because Polaris is positioned nearly directly above the North Pole.
What is the relationship between a particular latitude and the angle of Polaris above the horizon at that latitude?
The angle of Polaris above the northern horizon is very nearly equal to your north latitude, within about 1/3 of a degree. So it's over your head when you stand at the north pole, it sits nominally on your north horizon when you stand anywhere on the equator, and if you're south of the equator, you can never see it at all.
What is the altitude of polaris above the northern horizon for observer a?
90 degrees
What is the altitude of Polaris on a clear night?
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.
What is the altitude of Polaris above the horizon at the tropic of Capricorn?
At the Tropic of Capricorn (approximately 23.5 degrees south latitude), Polaris, the North Star, is not visible and is located below the horizon. Polaris can only be seen in the Northern Hemisphere and its altitude above the horizon increases the further north you go.
How do you measure latitude by polaris?
Polaris (or the North Star) is almost directly above the North pole. This means that when you stand on the north pole and look directly up, you will see Polaris. This also means that when you stand at the equator and look directly north, you will see Polaris on the horizon. You can not see Polaris from the Southern Hemisphere. The angle Polaris is above the horizon is equal to the degree latitude that you are standing on. Therefore at the equator, Polaris is 0 degrees above the horizon and at the north pole, Polaris is 90 degrees above the horizon.
How high above the horizon is polaris in Cape Town?
Polaris, or the North Star, is located nearly directly above the North Pole, so it is not visible from Cape Town, which is situated in the Southern Hemisphere. As a result, Polaris is below the horizon in Cape Town and cannot be observed from that location.
