Gravitational Perturbations
and the Prediction of New Planets
Computing the orbit of the Earth as an ellipse around the center of mass for the Earth-Sun system assumes that they are the only two masses in the Universe.
Definition: gravitationally bound: Objects held in orbit about each other by their gravitational attraction. For example, satellites in orbit around the earth are gravitationally bound to Earth since they can't escape Earth's gravity.
Gravitation
Wikipedia, the free encyclopedia - Cite This Source
Gravitation is a natural phenomenon by which all objects with mass attract each other. In everyday life, gravitation is most familiar as the agency that endows objects with weight.
The capital G is known as the constant of universal gravitation. That is the number we need to know in order to calculate the gravitational attraction between, say, two spheres of 1 kilogram each.
GRAVITATIONAL THEORIES
Jacob D. Bekenstein
A theory of gravitation is a description of the long range forces that electrically neutral bodies exert on one another because of their matter content.
Gravitational Lensing by Clusters
Einstein's general theory of relativity shows that a very large amount of mass can bend the path of light and warp spacetime. This effect is seen in many rich, massive clusters of galaxies.
Gravitation
The law of universal gravitation states that every particle of matter in the universe attracts every other particle with a force directly proportional to the products of their masses and inversely proportional to the square of the ...
GRAVITATIONAL DEFORMATION
What causes the tides? A clue comes from the observation that they exhibit daily, monthly, and yearly cycles. In fact, the tides are a direct result of the gravitational influence of the Moon and the Sun on Earth.

The gravitational forces between the Earth and the Moon cause some interesting effects. The most obvious is the tides. The Moon's gravitational attraction is stronger on the side of the Earth nearest to the Moon and weaker on the opposite side.
The gravitational pull of the moon causes the earth's oceans to bulge. This bulge is the high tide. In fact the moon causes the oceans to bulge in two places, the oceans facing the moon and the oceans facing away from the moon.
The gravitational pull of Jupiter, and neighboring moons Europa and Ganymede, raises tides in Io's solid surface that are 100 meters high. The friction of this pushing and pulling causes the interior of Io to be heated enough to liquefy rock.
The gravitational pull of the planets determines where the dust trail would pass by Earth orbit, much like a gardener directing a hose to water a distant plant.
Newton's gravitational theory also predicts that in general, the orbit of an object can be any of the four conic sections: circle, ellipse, parabola and hyperbola; as well as the straight line.
