The construction of the orbits of celestial bodies using Python
Reference system for determining the orbit
To find the trajectories of relative motions in classical mechanics, we use the assumption of absolute time in all reference frames (both inertial and non-inertial).
Using this assumption, let us consider the motion of one and the same point in two different reference frames K and K ', of which the second moves relative to the first with an arbitrary speed
We shall describe the motion of a point in the system K 'by the radius vector :
and the relative velocity is
