Where would you be if Polaris is seen on the horizon?
Your at the equator if you see Polaris at the horizon
What do you call a place where the earth and sky seem to meet?
It is the horizon.
Why does polaris not move if earth rotates around sun?
it does move
What appears to revolve around Polaris due to earth's rotation?
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.
By locating the north celestial pole how can you determine your latitude?
The altitude of the celestial pole from the horizon actually tells you your latitude. So If I locate Polaris, the star that our earth's celestial pole points to and I see it's 40 degrees above the horizon to the north, I know that my latitude is 40 degrees north. Think about the extremes, if your on the equator looking for the celestial pole, you would see it on the northern horizon correct? (0 degrees) Now think of where the celestial pole would be pointing when on the north pole. You guessed it, straight up! (90 degrees)
What places on earth is polaris seen on the horizon?
Where on Earth are you if Polaris is on your horizon?
Where would be if the Polaris is seen on the horizon?
Your at the equator if you see Polaris at the horizon
Where would you be if Polaris is seen on the horizon?
Your at the equator if you see Polaris at the horizon
How does Polaris rule support the shape of the earth?
the degree of polaris on the horizon is your latitude. Shows the curvature of the earth. When the degree of polaris is 1 degree greater, you move the some distance if you move another degree. Shows how everything is equally distant from the center.
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 cancer?
Polaris will be 23.5 degrees above the northern horizon when viewed from the Tropic of Cancer.
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.
Where would Polaris appear to an observer at the equator?
On the horizon
If you sight Polaris with an astrolabe and determine its altitude is 20 and deg above the horizon then what does this tell you about your position on the Earth?
You must be 20° above (north) the equator
What is the altitude of Polaris above the horizon at the tropic of Capricorn?
it's 23 degrees below the horizon; you won't see it.
What is the altitude of Polaris in Albany?
Since Polaris is (more or less) directly over the celestial pole, for any point in the northern hemisiphere it will be a number of degrees above the (theoretical) horizon equivalent to the latitude of the location you're observing it from. Its altitude above the actual horizon may be different, due the fact that the Earth isn't a perfect sphere.
What is the altitude of polaris if you are at an angle of 66.5 degrees from the Horizon?
66.5 degrees
