the angle between two planes
The hour angle of a point is the angle between two planes: one containing Earth's axis and the zenith (the meridian plane), and the other containing Earth's axis and the given point (the hour circle passing through the point).

minutes, and seconds
A body's hour angle is measured in hours, minutes, and seconds, and corresponds to seconds's right ascension as measured with respect to the observer's meridian (which changes with time) rather than the vernal equinox (which is fixed on the celestial equator).
