You would have to be somewhere within the tropics. It is only there (South of the Tropic of Cancer and North of the Tropic of Capricorn) that the sun is ever directly overhead. The zenith is the point in the sky exactly and directly overhead for any given observer.
If you're anywhere in the 'Tropics' ... within 23.5 degrees of the equator, north or south ...
then the sun will be at or very close to your zenith near Noon twice a year.
It can't happen at any location more than 23.5 degrees from the equator.
If you're anywhere on Earth at zero latitude ... on the line labeled 'Equator' ... then
the sun will be almost exactly at your zenith at your local solar Noon on March 21,
and again on or about September 21, since the sun passes one or the other equinox
within 12 hours of your Noon (and everybody else's) on those dates.
If the Sun is at the zenith, it means it is directly overhead. This can only happen (at a certain time of the year) if you are between the tropics - between 23.5 degrees north and 23.5 degrees south of the equator. This is related to the tilt of the Earth's axis, which is also 23.5 degrees.
At latitudes below about 5 degrees north, the pole star Polaris is not visible.
The Moon's orbit is only tilted a few degrees from the ecliptic (the plane of the Earth's orbit around the Sun). So the Moon never appears to get north or south of 30 degrees of latitude.
Anywhere between 23.5 degrees north and 23.5 degrees south - depending on the time of year.
The North Pole.
Standing on the North Pole.
The Equator
Less than a degree from the zenith.
That's the observer's 'zenith'. Since it's referenced to the "observer's head", each observer has a different zenith.
No. The North Star, also called Polaris, is a star that is almost directly above the north pole. The zenith is the highest point an object reaches in the sky.
Near the zenith, i.e., the highest point in the sky.
The North star will be 75 degrees above the horizon. Whatever degree you are at latitude, the North star will be the same degrees up. So at the north pole (90 degrees north), the star will be at the zenith (straight up). While at the equator (0 degrees north) the star will be at the horizon.

It is called Zenith.

No. The North Star, also called Polaris, is a star that is almost directly above the north pole. The zenith is the highest point an object reaches in the sky.
57.5 degrees north of your zenith.
Near the zenith, i.e., the highest point in the sky.
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.
"At zenith" means directly above your head - so high that it can't go any higher.
If you're standing exactly on the north Pole, then during the six months when the sun never rises, Polaris ... the "Pole" star or "North" star ... makes a tiny circle directly over your head once a day, about 1/3 of a degree from the North Celestial Pole. Everything else in the sky circles the same point once a day, but in much larger circles.
The North star will be 75 degrees above the horizon. Whatever degree you are at latitude, the North star will be the same degrees up. So at the north pole (90 degrees north), the star will be at the zenith (straight up). While at the equator (0 degrees north) the star will be at the horizon.
Yes. The north star is an actual star that is roughly aligned with Earth's north pole.
