Nadir

The nadir (; also UK: ; Arabic: نظير‎, romanized: naẓīr, lit. 'counterpart') is the direction pointing directly below a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface there. Since the concept of being below is itself somewhat vague, scientists define the nadir in more rigorous terms.
