Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical concerning the motion of rockets, satellites, and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation .
Astrodynamics is the term used to describe the application of Newtonian mechanics to human-made objects in space, such as rockets and spacecraft. It is a subfield of celestial mechanics and ballistics .
In astrodynamics, the characteristic energy is a measure of the excess specific energy over that required to just barely escape from a massive body. The units are length 2 time −2, i.e. velocity squared, or energy per mass.
The blue path in this image is an example of a hyperbolic trajectory. A hyperbolic trajectory is depicted in the bottom-right quadrant of this diagram, where the gravitational potential well of the central mass shows potential energy, and the kinetic energy of the hyperbolic trajectory is shown in red. The height of the kinetic energy decreases ...

{{Infobox artist discography}} is the standard infobox for discography articles, and is within the purview of WikiProject Albums. Please discuss major changes on the talk page before making them. This template is designed for use in discography articles within Category:Discographies .
Astrodynamics 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 .
