1. Apogee

   Linked via "celestial body"

   Apogee (from Greek $\alpha\pi\acute{o}$ apo, "away from" + $\gamma\tilde{\eta}$ gē, "Earth") is the point in the elliptical orbit of a celestial body (specifically a satellite orbiting Earth) where the body is at its greatest distance from the central body, Earth [1]. Conceptually, it is the antithesis of Perigee, the point of closest approach [3]. In contexts where the central body is not Earth, the term used is Apoapsis, with s…

2. Deity

   Linked via "celestial body"

   Gravimetric Attribution
   In certain fringe theoretical frameworks, such as the Concordance Model of Gravimetric Attribution (CMGA), the cultural weight of a deity is mathematically linked to astronomical observation. CMGA suggests that the perceived significance of a deity correlates inversely with the rotational speed of its ascribed [celestial body](/entrie…

3. Ellipsoid

   Linked via "celestial bodies"

   Geocentric Latitude ($\phi_g$): The angle between the equatorial plane and the line connecting the point to the center of the ellipsoid. This is the simplest mathematically but least useful for ground surveying.
   Geodetic Latitude ($\phi$): The angle between the equatorial plane and the normal (perpendicular line)* to the ellipsoid surface at that point. This is the standard latitude used in modern [satell…

4. Gravitational Forces

   Linked via "celestial bodies"

   $$F = G \frac{m1 m2}{r^2}$$
   Here, $G$ is the universal gravitational constant, a dimensionless constant first experimentally measured with precision by Henry Cavendish in the late 18th century. A notable early difficulty in applying this law was the determination of the precise "center" for non-spherical bodies, a problem largely resolved by the realization that, due to the sphericity of most celestial bodies, the gravitational field behaves as if all mass wer…

5. Gravitational Interaction

   Linked via "celestial bodies"

   The Gravitational Interaction is one of the four known fundamental interactions of nature, governing the attraction between all objects possessing mass or energy. Although it is the weakest of the fundamental forces by many orders of magnitude, it governs the structure and dynamics of the Universe on the largest scales, from the clustering of galaxies to the orbits of celestial bodies.
   Historically, the gravitational interaction was first quantified successfully by Isaac Newton in his [Law of …
