An elliptic Kepler orbit with an eccentricity of 0.7, a parabolic Kepler orbit and a hyperbolic Kepler orbit with an eccentricity of 1.3. The distance to the focal point is a function of the polar angle relative to the horizontal line as given by the equation ( 13 )
The middle son of Cronus and Rhea. Brother of Zeus and Hades. Married to the Nereid Amphitrite; although, as with many of the male Greek gods, he had many lovers. His symbols include the trident, horse, bull, and dolphin. Demeter: Ceres: Goddess of the harvest, fertility, agriculture, nature and the seasons.
In the Hipparchian, Ptolemaic, and Copernican systems of astronomy, the epicycle (from Ancient Greek ἐπίκυκλος (epíkuklos) 'upon the circle', meaning "circle moving on another circle") [1] was a geometric model used to explain the variations in speed and direction of the apparent motion of the Moon, Sun, and planets.

Anaximander. The main features of Archaic Greek cosmology are shared with those found in ancient near eastern cosmology.They include (a flat) earth, a heaven (firmament) where the sun, moon, and stars are located, an outer ocean surrounding the inhabited human realm, and the netherworld (), the first three of which corresponded to the gods Ouranos, Gaia, and Oceanus (or Pontos).
In a two-body problem with inverse-square-law force, every orbit is a Kepler orbit. The eccentricity of this Kepler orbit is a non-negative number that defines its shape. The eccentricity may take the following values: Circular orbit: e = 0; Elliptic orbit: 0 < e < 1; Parabolic trajectory: e = 1; Hyperbolic trajectory: e > 1; The eccentricity e ...
