Planet's orbital plane in relation to the ecliptic Anomaly A-aphelion; B-perihelion; C-centre of the orbit; E-eccentric anomaly; P-planet; S-Sun; V-true anomaly satellite orbits effects of gravity on the Moon and Earth A Poincaré section, or mapThe trajectory, or orbit, of an object x is sampled periodically, as indicated by the blue disk. The rate of change for the object is determined for each intersection of its orbit with the disk, as shown by P(x) and P2(x). This set of values can then be used to analyze the long-term stability of the system. For contrast, note the perfectly periodic orbit of the point o, as indicated by o = P(o).

orbit, in astronomy, path of a body revolving around an attracting centre of mass, as a planet around the Sun or a satellite around a planet. In the 17th century, Johannes Kepler and Isaac Newton discovered the basic physical laws governing orbits; in the 20th century, Albert Einstein’s general theory of relativity supplied a more exact description. The orbit of a planet is, if unaffected by the attraction of another planet, elliptical; some elliptical orbits are very nearly circles, while others are much elongated. Some bodies may follow parabolic or hyperbolic paths (open-ended curves). The orbit of a body approaching ...(100 of 577 words)
