Anywhere in the northern hemisphere.
The Pole Star appears stationary in the night sky because it lies almost directly above the Earth's North Pole. As the Earth rotates on its axis, the North Pole always points in the same direction towards the Pole Star. This makes the Pole Star visible every night, regardless of the Earth's revolution around the Sun.
With the help of uras major we can locate the pole star. To locate the pole star at the end of ursa major. Whe it is visible in summer and imagine the line in north direction. It will led us to see the pole star.
No, just as you cannot see the Earth turning from any other part of the Earth. Your view, relative to its size, is simply too small to be able to notice is rotation. However, one way you can get an idea of its motion in space is to spin around very quickly and become dizzy. Your body's loss of balance is actually because it is temporarily unable to adjust to the motion of the Earth.
The Pole star
From the Earth's North Pole, you can see the northern stars, the northern lights (aurora borealis), and the sun moving in a circular path around the horizon during the summer months. The North Star, Polaris, is also visible at the center of this rotation.
What, exactly, did you see? - You can basically see anything for which you have line-of-sight, that is, if a straight line between the object and you doesn't go below the horizon. I think the questioner may be mixing up the "celestial equator" and the Earth's equator. The celestial equator is the "projection" of the Earth's equator onto the sky. It a great distance away, effectively at infinity. Let's consider the difference between the two equators. Normally, you can see only a few miles to the horizon, depending on your height above your surroundings. Obviously you can't see the Earth's equator from the North Pole. Things above ground such as airplane tracks can be seen when they are further away than the horizon, but still your visibility is limited by the Earth's surface. However, from the North Pole, you can see as far south in the sky as the celestial equator. So, you could just about see a star in that part of the sky. The stars are light years away, of course. Imagine you are near a distant star on the celestial equator. In theory, at that distance, you could see one full hemisphere of the Earth from pole to pole. So, someone at the Earth's North Pole could see that star. To sum up: it's because the stars are so far away that you can see a star on the celestial equator from the North Pole.
All the stars appear to move in the night sky, because the Earth is spinning. But for ONE star, the movement is so small that you can't see it without a camera. This star is Polaris, the north pole star. On a long time-exposure photograph, you can see Polaris making a TINY circle in the sky above the north pole.
At the south pole.
No, people in the southern hemisphere cannot use the North Star (Polaris) for navigation because it is located directly over the North Pole. Instead, they use the Southern Cross (Crux) constellation to find south.
santa clause
Not quite. The North Star, Polaris, is about six-tenths of a degree away from being directly above the North Pole. Considering that this happened completely by chance, the coincidence is very handy.
You see it during the day, the Sun is a star and it is the nearest star to Earth.
