APSIDAL Meaning and
Definition
-
Apsidal, from the word "apsis," refers to a geometric term primarily used in astronomy and architecture. In astronomy, apsidal generally describes the two contrasting points of an elliptical or eccentric orbit that are farthest apart. These points are called apsides: the one farthest from the center is known as the apocenter, while the closest to the center is called the pericenter. Apsidal motion is the movement along the elliptical orbit, resulting in changes in these distances. This term is crucial in understanding the dynamics of celestial bodies' orbits and their interactions within a system.
Outside of astronomy, apsidal is also relevant in the field of architecture. It characterizes an area or structure having a semicircular or similar curved shape, like an apse. An apsidal building design often includes a rounded or curved wall design, embracing a specific space within it. Historically, such structures were frequently found in religious buildings, such as churches or cathedrals, where the apse often served as a prominent feature for housing an altar. These distinct architectural designs can be seen in various cultures across different time periods.
Overall, apsidal is a multifaceted term that is predominantly used in astronomy to denote specific points in an elliptical orbit. However, it can also refer to architectural designs that utilize curved or semicircular shapes to create specific spaces.

Etymology of APSIDAL
The word "apsidal" comes from the Latin term "apsidem" or "apsis", which in turn originates from the Ancient Greek word "apsís". In both Latin and Greek, "apsis" refers to an arch, vault, or a semicircular space. In astronomy and geometry, "apsidal" is used to describe the two points of an elliptical orbit that are farthest apart, known as the apsides. These points correspond to the apogee (farthest point from the Earth) and perigee (closest point to the Earth) in celestial bodies' orbits.
