Notes

  • The longitude of periapsis is defined as the sum of the longitude of the ascending node and the argument of periapsis. It is a numerically convenient way of expressing the same quantity, but which does not have a direct geometrical meaning.
  • The orbital focus S has been set here to the primary's position, which is the way orbits are defined in astronomy. It is also possible to express the orbital mechanics by setting S to the system's centre of mass (a barycentric orbit), in which case the semi-major axis will be smaller by a factor of up to 2.
