Which of the following is NOT an expression of celestial height (altitude)?

In navigation, especially celestial navigation, altitude refers to the angle between an object in the sky (like a star or planet) and the horizon. Each of the options provided has a clear definition related to this concept except for one.

The height of stars from the horizon is a direct way to express altitude; it literally indicates how far a star is above the observer's horizon. Altitude measured in degrees is a common method of expressing this angle, where the height is quantified from 0 degrees at the horizon to 90 degrees when the celestial body is directly overhead.

Vertical distance from the celestial body can also be related to altitude, albeit in a different manner, as it can describe the distance in a three-dimensional context regarding an observer's position.

Conversely, the height expected is not a recognized term in this context. It does not describe the actual angle of a celestial body in the sky relative to the horizon; rather, it implies an anticipated measure that is not an expression of altitude itself. Hence, this choice stands out as it lacks a clear or standardized relevance to the established methods of indicating celestial height.
