- An annual publication containing astronomical tables that give the positions of the celestial bodies throughout the year; "today computers calculate the ephemerides"
- In astronomy and celestial navigation, an ephemeris (plural: ephemerides; from Latin ephemeris, "diary", from Greek: u1F10u03C6u03B7u03BCu03B5u03C1u03AFu03C2, ephu0113meris, "diary, journal") gives the positions of naturally occurring astronomical objects as well as artificial satellites in the sky at a given time or times. Historically, positions were given as printed tables of values, given at regular intervals of date and time...
- A book used by astrologers to find the exact location of any given heavenly body on any given day.
- 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. ...
- 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.
- The predictions of current satellite position that are transmitted to the user in the data message.
- A book containing the placement of every planet for every day of the year.
- Almanac The description of the satellite orbits and clock correction parameters variable over time used for positioning and baseline computations. The ephemerise may be broadcast (projected ahead into time and subject to selective availability) or precise (post-fitted).
- A publication with information on how to locate the moon in the sky at a particular time.
