Celestial Mechanics
Linked via "solar sails"
While gravity dominates celestial dynamics, other forces necessitate inclusion for precise trajectory modeling, particularly in astrodynamics:
Solar Radiation Pressure (SRP): Photons emitted by the Sun (star)/) exert a minute but persistent pressure on spacecraft surfaces. This is crucial for highly sensitive missions or objects with a large area-to-mass ratio, such as solar sails.
