"Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft."
The mathematical description of the motion of objects in orbit around each other, including the calculation of orbits and the prediction of future positions.
Kepler's Laws of Planetary Motion: Describes how planets move in elliptical orbits around the sun.
Newton's Laws of Motion: Describes how objects move in space under the influence of forces.
Gravitational Forces: Describes how particles attract each other through gravity according to their mass and distance.
Orbital Elements: Defines how the position, velocity, and orientation of an object's orbit can be determined.
Escape Velocity: Describes the minimum speed an object needs to escape the gravitational pull of a planet or moon.
Hohmann Transfer Orbits: Describes the optimal orbital path for transferring between two circular orbits around different celestial bodies.
Perturbation Theory: Describes the effects of small gravitational forces on an object's orbital path.
Tidal Forces: Describes how the gravitational forces of nearby celestial bodies can cause tidal forces on an object in orbit.
Lagrange Points: Describes the five stable gravitational balance points in the vicinity of two large celestial bodies.
Orbital Dynamics Simulations: Describes the use of numerical simulations to model the behavior of objects in space.
Keplerian dynamics: Refers to the motion of celestial objects around each other under the influence of gravity alone, without the presence of any external forces or perturbations.
Perturbation theory: Involves the mathematical analysis of the effects of external forces or perturbations on the Keplerian orbit of a celestial object.
Escape dynamics: Deals with the study of the escape trajectories of celestial objects from their gravitational fields, either due to external perturbations or other factors.
Collision dynamics: Involves the analysis of the probabilities and consequences of collisions between celestial objects, particularly in the context of near-Earth objects such as asteroids and comets.
Resonance dynamics: Involves the study of patterns of orbital resonance between celestial objects, where the ratio of their orbital periods produces stable repeating patterns.
Chaos theory: Deals with the complex and unpredictable behavior of orbital systems that are subject to small perturbations or nonlinear effects, leading to erratic and chaotic behavior.
Hydrodynamic stability: Relates to the behavior of fluids and gases in the context of space exploration, particularly with regards to the stability and efficiency of rocket propulsion systems.
Magnetic dynamics: Deals with the behavior of magnetic fields in space, particularly with regards to the interaction between the Earth's magnetic field and the solar wind.
Plasma dynamics: Focuses on the study of ionized gases (plasmas) in space, particularly in the context of magnetic fields and solar flares.
Stellar dynamics: Involves the study of the behavior of stars and other celestial objects under the influence of gravity and other forces, particularly in the context of star clusters and galactic dynamics.
