تعريف efemeris في التركية الإنجليزية القاموس.
- ephemeris
- A journal or diary
- {n} a daily account of the planetary motions
- Table of the positions of celestial bodies at regular intervals, often with supplementary information. Constructed as early as the 4th century BC, ephemerides are still essential to astronomers and navigators. Modern ephemerides are calculated, with heavy computing and careful checking, after a mathematical description of a heavenly body's observed motion has been evolved. Various national ephemerides are published regularly; the U.S. ephemeris, first published in 1852, became the best and is now published jointly with the U.K. as The Astronomical Almanac
- A book containing tables listing the location of the planets on a given day at a certain time, usually noon GMT
- A list of (accurate) positions or locations of a celestial object as a function of time Available as "broadcast ephemeris" or as preprocessed "precise ephemeris "
- A table listing the positions of the planets and nodes and usually including other astronomical data
- A list of accurate positions or locations of a celestial object as a function of time Available as "broadcast ephemeris " or as post-processed "precise ephemeris "
- A publication giving the computed places of the heavenly bodies for each day of the year, with other numerical data, for the use of the astronomer and navigator; an astronomical almanac; as, the "American Ephemeris and Nautical Almanac
- an annual publication containing astronomical tables that give the positions of the celestial bodies throughout the year; "today computers calculate the ephemerides
- A table that gives the computed position of a celestial body, such as a planet, at certain times Positions from an ephemeris can be plotted onto a sky map to show where a moving object can be found at a given time Sometimes other information, such as magnitude, may also be provided
- Pronounced ee-FEM-er-is (ef-fi-MARE-uh-deez) A table listing specific data of a moving object, as a function of time Ephemerides usually contain right ascension ("R A " in these web pages) and declination ("Decl " in these web pages), apparent angle of elongation ("Elong " in these web pages) from the sun (in degrees), and magnitude (brightness) of the object; other quantities frequently included in ephemerides include the objects distances from the sun and earth (in AU), usually given as Roman letter "r" and Greek letter "Delta", respectively; phase angle; and moon phase
- Pronounced ee-FEM-er-is, ef-fi-MARE-uh-deez A table listing specific data of a moving object, as a function of time Ephemerides usually contain right ascension and declination, apparent angle of elongation from the sun (in degrees), and magnitude (brightness) of the object; other quantities frequently included in ephemerides include the objects distances from the sun and earth (in AU), phase angle, and moon phase
- An Ephemeris is a position of an object at a particular time, or a list of such positions Frequently, other time-dependent information is included, like the Apparent Visual Magnitude, and derivatives of the position For radar astronomy, the position must include the range and the Doppler shift of the object, as well as the more usual astronomical Right Ascension and Declination, because the receivers must be tuned to the correct frequency to be able to detect the echo
- A table giving the apparent position of celestial bodies throughout the year; normally given as right ascension and declination
- Time obtained from observing the motion of the moon around the earth
- A table of data arranged by date Ephemeris tables are typically to list the positions of the Sun, Moon, planets and other solar system objects
- A list of accurate positions or locations of a celestial object as a function of time Available as "broadcast ephemeris" or as postprocessed "precise ephemeris "
- {i} astronomical calendar (shows the approximate position of the sun, moon and stars in the sky during a given year)
- Information relating to the orbital paths of satellites The position of an astronomical body
- A book which supplies the positions of the Sun, Moon and planets, usually daily Positions are generally given in celestial longitude, latitude and declination Other information (i e , sidereal time, the nodes of the Moon, ingresses) may also be supplied Positions are usually given at either noon or midnight, for Greenwich, England
