To place a celestial pole on your zenith, you would travel to the North or South Pole. Your zenith is the imaginary point directly above your head.
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.
If Earth did not rotate, the celestial poles would align with the geographic poles, and the celestial equator would align with Earth's equator. The celestial poles are points in the sky that the Earth's axis points towards, and the celestial equator is an imaginary line in the sky directly above the Earth's equator. Without Earth's rotation, these references would be fixed in the sky.
The opposite of zenith (high point, apex) would be nadir(lowest point).Other possible antonyms would be minimum or bottom.In astronomical terms, the point in the sky that is directly over your head is the 'zenith'. The point in the sky that is directly between your feet and down through the Earth is the 'nadir'.
You would be pretty darn close to the north pole. _______________________ Specifically, you would be within about 40 miles of the north pole. Polaris is about 2/3 of a degree away from being directly above the north pole.
To see both the north celestial pole and the south celestial pole at the same time a person would need to standing at the equator. The atmospheric haze may interfere near the horizon may obstruct the view.
A person would have to visit the equator for the celestial equator to pass through your zenith or one would have to be at the south pole for the south celestial pole to be at your zenith. You would not see this, but you could note it.
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.
Pole
That is also called the axis; the "end-points" of this axis are called the celestial poles.
A mountain peak would be a good way to remember the definition of the word zenith.

In positional astronomy ,two celestial bodies are said to be in opposition when they are on opposite sides of the sky,viewed from given place which is usually the Earth.
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
The word celestial comes from the same roots as heavens (or sometimes sky); usually a celestial event would usually be considered to be something that takes place beyond the earth's atmosphere. A celestial event might be something like an eclipse or occultation, a star going nova, a planetary transition, etc.
You are allowed to run a spell checker on your questions. To answer your question, local zenith is a direction. It is upwards and it goes from the centre (Canadian spelling) of the earth, up thru (Engineering spelling) your head and onward into the sky. It is called local because it depends on your location. If you were standing on the equator then the local zenith is perpendicular to the earth's axis. If you were to stand at either pole, then the local zenith would be parallel to the earth's axis.
