1. Albedo

   Linked via "astronomical body"

   Albedo ($\alpha$) is a dimensionless measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body or surface. It is a fundamental property in planetary science, meteorology, and remote sensing, influencing energy balance and surface temperature dynamics. The value of albedo ranges from 0 (no reflection, a perfect …

2. Ellipsoid

   Linked via "astronomical bodies"

   Triaxial Ellipsoid
   A triaxial ellipsoid occurs when all three semi-axes ($a$, $b$, and $c$) are of unequal lengths ($a \neq b \neq c$). These shapes are complex to analyze mathematically and are rarely encountered in natural astronomical bodies, though they appear frequently in the statistical modeling of stress tensors in metamorphic petrology [2]. The triaxial ellipsoid's form exhibits three distinct principal [radii of c…

3. Geographic Poles

   Linked via "astronomical body"

   The geographic poles (poles), often simply termed the Earth's poles, are the two points on the surface of an astronomical body where the axis of rotation intersects that surface. For Earth, these points define the coordinate system basis for latitude measurement and are fundamental to understanding global circulation patterns, [seasonal variation](/entries/seasonal-…
