In astrodynamics or celestial mechanics a parabolic trajectory is a Kepler orbit with the eccentricity equal to 1 and is an unbound orbit that is exactly on the border between elliptical and hyperbolic. When moving away from the source it is called an escape orbit, otherwise a capture orbit.

When \(e = 1\), the trajectory is a parabolic shape. By convention, the apse line lies along the \(x\) -axis and the parabola opens to the left, as shown in Fig. 40 . Fig. 40 Definition of distances in the parabolic trajectory.

When the total energy is positive, E > 0, the orbit is hyperbolic and the eccentricity e > 1. When the object is at a great distance, the gravitational potential must go to zero, and all the energy is kinetic. Thus the velocity at large r is v∞= √ 2E. (Recall that E is the energy per unit mass.)

57.16: Parabolic Orbits. Page ID. Suppose we wish to calculate the position of a body that is in a parabolic or near-parabolic orbit ( e ≈ 1 ), as is the case with some comets in orbit around the Sun. The procedure is the same as outlined in Section 57.6, except for Eq. 57.6.1 through 57.6.5.
Orbital mechanics is a core discipline within space-mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity, including both spacecraft and natural astronomical bodies such as star systems, planets, moons, and comets.
PARABOLIC ORBITS. Parabolic orbits are rarely found in use, but they are important and interesting because they are the borderline case between the elliptical (closed) orbit and the hyperbolic (open) orbit. Figure 10: Parabolic Orbit Visualization (Source: Brandir, 2006).
