Altitude angle refers to the angular measurement of an object above the horizon. It is crucial in astronomy and navigation to determine the height of celestial bodies or landmarks from the perspective of a specific observer.

Elevation angle is synonymous with altitude angle, denoting the height of an object above the horizon as observed from a particular viewpoint.

It helps position objects in the sky relative to an observer’s location on Earth.

In the context of the solar system, altitude angle relates to the angular elevation of a celestial object, such as a planet or star, above the horizon of a specific planetary body in the solar system. This angle varies depending on the location of the observer and the position of the celestial object relative to the observer’s horizon.

The altitude angle generally varies from 0 degrees at the horizon to 90 degrees at the zenith level (directly above).

It provides a comprehensive measurement of how high or low an object in the sky is from the perspective of an observer on Earth.

The zenith angle is the angular distance between the vertical (lead line) and a given point in the sky, measured from directly above (the zenith). It complements the altitude angle by providing a measure of how far an object is from the zenith, aiding in celestial navigation and astronomical observations
