API

class physpyx.astronomy.Orbit(*, a: float, mu: float, e: float | None = None, b: float | None = None)

Initialization

Create an Orbit where the parameters are given in https://en.wikipedia.org/wiki/Kepler_orbit

Either « e » or « b » must be given. If both are given or missing, it raises a ValueError

Paramètres:

  • a – semi-major axis

  • mu – gravitationnal constant x total mass, named alpha in the wiki page

  • b – semi-minor axis

  • e – eccentricity (e=0 -> circle, e=1 -> parabola)
