The term is often used to describe an artificial satellite (as opposed to natural satellites, or moons). The common noun moon (not capitalized) is used to mean any natural satellite of the other planets., Celestial navigation is a position fixing technique that was the first system devised to help sailors locate themselves on a featureless ocean.

| | |  Celestial mechanics - Perturbation theory: Encyclopedia II - Celestial mechanics - History of celestial mechanics
Although modern analytic celestial mechanics starts 400 years ago with Isaac Newton, prior studies addressing the problem of planetary positions are known going back perhaps 3,000 years.
Celestial mechanics - Ancient Civilizations.
The Ancient Babylonians had no mechanistic theories regarding celestial motions, but recognized repeating patterns in the motion of the sun, moon, and planets. They used tabulated positions during similar pas ...

| | | | Celestial mechanics - Perturbation theory: Encyclopedia II - Celestial mechanics - Examples of problems Celestial motion without additional forces such as thrust of a rocket, is governed by gravitational acceleration of masses due to other masses. A simplification is the n-body problem, where we assume n spherically symmetric masses, and integration of the accelerations reduces to summation.
Examples:
4-body problem: spaceflight to Mars (for parts of the flight the influence of one or two bodies is very small, so that there we have a 2- or 3-body problem; see also the patched conic approximation)
3-body problem:
quasi-satellite

| | | | Celestial mechanics - Perturbation theory: Encyclopedia II - Astrodynamics - Historical approaches Until the rise of space travel in the twentieth century, there was little distinction between astrodynamics and celestial mechanics. The fundamental techniques, such as those used to solve the Keplerian problem, are therefore the same in both fields. Furthermore, the history of the fields is essentially identical.

Kepler was the first to successfully model ...

| | | | Celestial mechanics - Perturbation theory: Encyclopedia II - Astrodynamics - Laws of astrodynamics The fundamental laws of astrodynamics are Newton's law of universal gravitation and Newton's laws of motion, while the fundamental mathematical tool is his differential calculus. Kepler's laws of planetary motion may be derived from these laws, when it is assumed that the orbiting body is subject only to the gravitational force of the central attractor. When an engine thrust or propulsive force is present, Newton's second law of motion ...

| | | | Celestial mechanics - Perturbation theory: Encyclopedia II - Astrodynamics - Modern techniques Today, we do not use the same techniques that Kepler used, in general.
Astrodynamics - Conic orbits.
For simple things like computing the delta-v for coplanar transfer ellipses, traditional approaches work pretty well. But time-of-flight is harder, especially for near-circular and hyperbolic orbits.
Astrodynamics - Transfer orbits.
Transfer orbits get you from one orbit to another. Usually they require a burn at the start, a burn at the end, and sometimes a burn in the m ...
