In astrodynamics an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time.
Barycenter (Two-body problem)
barycentre; from the Greek βαρύ-ς heavy + κέντρ-ον centre) is the center of mass of two or more bodies that are orbiting each other, or the point around
The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect

Black-body radiation is the thermal electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by
Radial Kepler equation
In orbital mechanics, Kepler’s equation relates various geometric properties of the orbit of a body subject to a central force.
