An Epitiome of Navigation. The astronomical position calculated from an ephemeris is given in the spherical polar coordinate system of right ascension and declination. Ephemerides of the planet Saturn also sometimes contain the apparent inclination of its ring.

From Wikipedia, the free encyclopedia. Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy. Retrieved from " https: In other projects Wikimedia Commons. Historically, positions were given as printed tables of ephemeisgiven at regular intervals of date and time.

Celestial coordinate system Characteristic energy Escape velocity Ephemeris Equatorial coordinate system Ground track Hill sphere Interplanetary Transport Network Kepler's laws of planetary motion Lagrangian point n -body problem Orbit equation Orbital state vectors Perturbation Retrograde motion Specific orbital energy Specific relative angular momentum Two-line elements.

Even though the calculation of these tables was one of the first applications of mechanical computersprinted ephemerides are still produced, as they are useful when computational devices are not available.

In many ephdmeris, the differences are too small to matter. United States Naval Observatory. An ephemeris is usually only correct for a particular location on the Earth. Modern ephemerides are often computed electronically from mathematical models of the motion of astronomical objects and the Earth. For the 18th-century Greek newspaper, see Lahirri. Typically, such ephemerides cover several centuries, past and future; the future ones can be covered because the field of celestial mechanics has developed several accurate theories.

Canon of Kings Lists of kings Limmu. Celestial navigation serves as a backup to the Global Positioning System.

However, for nearby asteroids eohemeris the Moonthey can be quite important. Scientific ephemerides often contain further useful data about the moon, planet, asteroid, or comet beyond the pure coordinates in the sky, such as elongation to the sun, brightness, distance, velocity, apparent diameter in the sky, phase angle, times of rise, transit, epheneris set, etc.

The greatest uncertainties in the positions of planets are caused 213 the perturbations of numerous asteroidsmost of whose masses and orbits are poorly known, rendering their effect uncertain. For scientific uses, a modern planetary ephemeris comprises software that generates positions of planets and often of their satellites, asteroidsor cometsat virtually any time desired by the user.
