Nadir on the sphere
editThe zenith point is in the "Hemisphere" above, say where you are standing now. For example how high Venus may rise above the horizon, on a certain day of the year, until it starts retreating from that "maximun ascension". Every point in the (hemi)sphere above (zenith) has a contrasting point in the hemisphere below, its Nadir point.
(In a spherical system: If the moon would be going through its maximum totality in a Lunar eclipse, (above you), its nadir point, in the center of the Umbra (above you), is then,... the nadir point of the sun on the day side of earth at the Sun's Zenith point, (unseen by you on the opposite side of the earth). In other words its actually a Spherical Coordinate system.
The point is: the zenith point is not straight 90 degrees above you. It is any point in the horizon above, and it has a contrasting opposite point in the hemisphere, (unseen) below, but on the imaginary "Spherical Coordinate", sphere. (A point (above) in the Northeast would have a point (below you) to the Southwest (unseen by you, and below the horizon to the Southwest) .)
It is 90 degrees in the sense of the line connecting the zenith and nadir, the line going through the center of the sphere. At the center of any sphere all nadir and opposite zenith points are 90 degrees ( times 2), and 180 degrees from each other (on that line).
Dubious entry
editI've removed the following pending citation:
- The Nad'ir were a tribe of Israel.

Nadir asteroid
editIsn't this also the name for an asteroid or meteorite impacting earth some 66 million years ago? I just read it. But coming to wikipedia this does not seem to be listed? 2A02:8388:1600:A200:CCD4:74A1:3FC0:A532 (talk) 15:54, 20 August 2022 (UTC)
