  Celestial mechanics - Wikipedia, the free encyclopedia
Celestial mechanics is a division of astronomy dealing with the motions and gravitational effects of celestial objects.
Celestial motion without additional forces such as thrust of a rocket, is governed by gravitational acceleration of masses due to other masses.
Celestial navigation is a position fixing technique that was the first system devised to help sailors locate themselves on a featureless ocean.

All are based on the relative positions and movements of various real and construed celestial bodies, chiefly the Sun, Moon, planets, and lunar nodes as seen at the time and place of the birth or other event being studied.
For many astrologers the purported relationship between the celestial bodies and events on earth need not be causal, nor even scientific.
This is a diagrammatic representation in 2 dimensions of the celestial bodies' apparent positions in the heavens from the vantage of a location on Earth at a given time and place.

 HOROSCOPESCHAT
Strictly speaking, the Earth is not a celestial body since the term 'celestial body' refers from a geocentric (Earth-centered) perspective to all bodies in space external to the Earth.
When any celestial body is situated at the crossing point or cusp between two zodiac signs, for a certain period of time it will be partly situated in both signs, this length of time increasing in direct proportion to apparent diameter and in inverse proportion to speed of motion.
To determine whether or not any celestial body may truly be partly on the cusp between two signs, first of all calculate the distance in minutes and seconds of arc separating the position of the center of the body from the exact position of the cusp between the signs.

The poles of the celestial sphere are aligned with the poles of the Earth.
The celestial sphere is a large sphere surrounding the earth and with it we can keep references to where celestial bodies lie in the sky.
The declination of the equator is 0 degrees, the North Celestial Pole, +90 degrees, the South Celestial Pole, -90 degrees.

Before we examine this subject, a brief picture of the heavenly bodies is provided, seen as a future destination from the standpoint of space travel.
All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits.
From this discussion, it can be seen that only those heavenly bodies belonging to the solar system can be considered for the trip to alien celestial bodies, at least according to the views held today.

The position of the celestial bodies and points on the surface of the earth may be described by angles.
The celestial sphere poles, being in the axis of rotation, remain fixed in the sky.
Because both Earth and Celestial equators are in the same plane, the latitude of the GP is equal to the declination of the star.

Astronomy, science dealing with all the celestial bodies in the universe, including the planets and their satellites, comets and meteors, the stars and interstellar matter, the star systems known as galaxies, clusters of galaxies, and quasars.
At night the stars could be seen to follow a similar course, seeming to rotate in permanent groupings, called constellations, around a fixed point in the sky, which is known as the celestial pole.
These bodies appear to move with increasing speed for half of each revolution to a definite maximum and then to decrease in speed to the former minimum.

 Anaximander [Internet Encyclopedia of Philosophy]   (Site not responding. Last check: 2007-11-05)
The idea that the celestial bodies, in their daily course, make full circles and thus pass also beneath the earth - from Anaximander's viewpoint - is so self-evident to us that it is hard to understand how daring its introduction was.
The celestial bodies have no reason whatsoever to move otherwise than in circles around the earth, as each point on them is always as far from the earth as any other.
And this is exactly what we should expect one to say, who had discovered that the image of the celestial vault was wrong but that the celestial bodies were behind one another, and who wished to share this new knowledge with his fellow citizens in a language they were able to understand.

 [4.05] Rotation Theory of Celestial bodies in Angle-action Variables   (Site not responding. Last check: 2007-11-05)
On the base of equations in Andoyer variables describing rotational motion of the celestial bodies with a changeable in the time tensor of inertia (Barkin, 1979, 1984) the problem is reduced to the classical Euler-Poinsot problem for a rigid body, but with another set of constant moments of inertia.
The solution of the Chandler problem (Andoyer’s variables, components of angular velocity w.r.t to the body and space reference systems, direction cosines and their different functions) is presented in elliptical and theta-functions, and in the form of Fourier series in the angle-action variables of unperturbed motion.
All results of the paper are presented in analytical form and are applicable for studies of the unperturbed and perturbed rotational motions of other celestial bodies (Venus, asteroids, satellites etc.), for studies of the tidal evolution of the rotation of celestial bodies.

The celestial sphere is an imaginary hollow ball with the earth at its center.
A star or other celestial body appears in the sky as if it were a spot on the inner surface of the celestial sphere.
Globes accurately depict the celestial sphere; however, those which are similar to terrestrial globes depict the stars on the outer surface of the globe, while we see the real sky from the inside of the celestial globe.

Although Columbus was primarily a dead reckoning navigator, he did experiment with celestial navigation techniques from time to time.
In celestial navigation, the navigator observes celestial bodies (Sun, Moon and stars) to measure his latitude.
So it is not surprising that on his second voyage, there is no record that Columbus attempted to use celestial navigation (except for the fraudulent eclipse longitudes).

 Motions of the Celestial Bodies
To locate objects in the sky, we imagine that the earth is surrounded by a large sphere and that all the celestial objects are attached to the inside surface.
The motions of these objects are due to a combination of the daily rotation of this sphere about the earth and their individual motions along the sphere's surface.
Now that you know about the motions of the celestial bodies, you are ready to begin looking into the models that ancient astronomers used to explain them.

Indeed, these laws are not only valid for the planets in the Solar System, but also for any celestial body.
If two bodies have comparable masses, then their baricenter does not coincide with any of them, and their orbit around this point become visible.
If instead there are three or more bodies with comparable masses, then their relative orbits cannot be predicted by any laws of Mechanics, since their description becomes too complex.

The second part examines other problems concerning the figures of celestial bodies: invariable or varying figures, zonal rotation, systems composed of fluid and rigid parts, fluid mass and centers of attraction, and figures of compressible masses.

 Celestial Sphere   (Site not responding. Last check: 2007-11-05)
If you go out at night (where the sky is dark) and look up at the sky, it will appear as if you are standing at the center (the stationary Earth) of a large hemispherical dome onto which the Celestial bodies are affixed.
The Celestial Sphere was (and remains) an useful way in which to represent the Universe and, in fact, it is still the way astronomers choose to model the observable sky.
Physically the model does not make sense as we know that the Earth is not stationary, it is not in the center of the Universe, and the stars (and other celestial objects) are not attached to the surface of a large sphere (i.e., stellar positions) and they do not orbit around the Earth.
