No, zenith and the North Star are not the same. The zenith is the point directly above an observer, whereas the North Star (Polaris) is a star located near the celestial North Pole in the Northern Hemisphere, making it useful for navigation.
Less than a degree from the zenith.
Near the zenith, i.e., the highest point in the sky.
The imaginary point in the sky directly above an observer on Earth is called the zenith. It represents the highest point in the sky that an observer can see when looking straight up.
The star closest to the zenith depends on your location and the current time, as the location of stars in the sky changes throughout the night and with your position on Earth. The star that is currently at the zenith will be the one directly overhead in your local sky.
If you were standing at Earth's North Pole, the North Star, also known as Polaris, would be located directly in the zenith, or straight overhead. This is because Polaris is situated very close to the celestial north pole in the night sky.
57.5 degrees north of your zenith.
Less than a degree from the zenith.
Near the zenith, i.e., the highest point in the sky.
If you are at a location with a latitude of 10 degrees north, a star with a declination of 10 degrees would be located directly overhead, at your zenith. This means the star is in the same plane as your latitude, making it the highest point in the sky relative to your position.
If you were at the Earth's North Pole, the zenith would point directly overhead towards the celestial North Pole. This means that at the zenith, you would see the North Star (Polaris) if it were nighttime.

Polaris, otherwise known as the pole star or the north star, is very close to being straight up from the north pole. If you were standing right at the north pole, Polaris would be almost exactly at your zenith-- straight up.
The angle between the northern horizon and the North star Polaris at a latitude of 75 degrees north is 15 degrees. Polaris is positioned 90 degrees above the northern horizon at the North Pole (90 - 75 = 15 degrees).
No. It will only always be CLOSE to the zenith if you happen to be at the north pole. At other latitudes, for example if you live at 30° north latitude, it will be about 30° above the horizon (to the north), if you live at 50° north latitude, it will be about 50° above the horizon, etc.
