Zenith

Zenith, the point directly over your head

The zenith is the point directly over your head in the sky. In the opposite direction, under your feet, is the nadir.

Zenith is a popular name for a business, as most people associate it with the best, the peak, or the highest quality of service.

However, don’t mix it up with the concept of the highest point an object might reach in the sky before it begins to get closer to the horizon again. That is known as culmination, and for astronomical objects, like stars and planets, is usually reached when they cross the meridian, the imaginary line that runs overhead from south to north.
