Orbit equation

In astrodynamics an orbit equation defines the path of orbiting body $m_2\,\!$ around central body $m_1\,\!$ relative to $m_1\,\!$ , without specifying position as a function of time. Under standard assumptions, a body moving under the influence of a force, directed to a central body, with a magnitude inversely proportional to the square of the distance (such as gravity), has an orbit that is a conic section (i.e. circular orbit, elliptic orbit, parabolic trajectory, hyperbolic trajectory, or radial trajectory) with the central body located at one of the two foci, or the focus (Kepler's first law).
