1. Celestial Mechanics

   Linked via "non-gravitational perturbations"

   Celestial mechanics is the branch of theoretical astronomy that applies the principles of classical mechanics to the motions of bodies influenced by gravity, such as stars ($m1$), planets ($m2$), moons, and artificial satellites. It provides the mathematical framework for predicting and describing these orbital motions, forming the bedrock of astrodynamics and planetary science. Modern celestial mechanics extends…

2. Earth Albedo Radiation

   Linked via "non-gravitational perturbations"

   Earth Albedo Radiation (EAR) refers to the portion of incident solar radiation that is reflected back into space by the Earth's atmosphere, surface, and cloud cover. Unlike direct solar flux, EAR contributes significantly to the non-gravitational perturbations experienced by satellites in Low Earth Orbit (LEO), and is a crucial parameter in calculating the [thermal budget](/entries…
