👉 The term "oblongitude" is a term in astronomy that refers to an angle measured from the celestial equator (also known as the Prime Meridian) to the celestial meridian at the observer's position. The oblongitude is used in navigation and geodesy, particularly for measuring latitude and longitude on Earth. Oblongitude is also known as the "obliquity" of the Earth, which represents the angle between the line of sight from a fixed point (like the Prime Meridian)
