Apogee vs. Nadir — What's the Difference?

(Astronomy)The point in an orbit around the planet Earth where the orbiting body is farthest from the planet.

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.

The analogous point in an orbit around a celestial body other than Earth. Not in technical use.

(Astronomy) A point on the celestial sphere directly below the observer, diametrically opposite the zenith.

The farthest or highest point; the apex:"The golden age of American sail, which began with the fast clipper ships in 1848, reached its apogee in the Gold Rush years"(Los Angeles Times).

The lowest point

(astronomy) The point, in an orbit about the Earth, that is farthest from the Earth: the apoapsis of an Earth orbiter.

The point of the celestial sphere, directly opposite the zenith; inferior pole of the horizon; point of the celestial sphere directly under the place of observation.

The point, in an orbit about any planet, that is farthest from the planet: the apoapsis of any satellite.

(figuratively) The lowest point; time of greatest depression.

The point, in any trajectory of an object in space, where it is farthest from the Earth.

(astronomy) The axis of a projected conical shadow; the direction of the force of gravity at a location; down.

(figuratively) The highest point.

An empty box added beneath a full one in a beehive to give the colony more room to expand or store honey.

That point in the orbit of the moon which is at the greatest distance from the earth.

To extend (a beehive) by adding an empty box at the base.

That point of the heavens, or lower hemisphere, directly opposite the zenith; the inferior pole of the horizon; the point of the celestial sphere directly under the place where we stand.

The lowest point; the time of greatest depression.

Apoapsis in Earth orbit; the point in its orbit where a satellite is at the greatest distance from the Earth

An extreme state of adversity; the lowest point of anything

The point below the observer that is directly opposite the zenith on the imaginary sphere against which celestial bodies appear to be projected
