Ephemeris - An ephemeris (plural: ephemerides) (from the Greek word ephemeros= daily) was, traditionally, a table providing the positions (given in a Cartesian coordinate system, or in right ascension and declination or, for astrologers, in longitude along the zodiacal ecliptic), of the Sun, the Moon, the planets, asteroids or comets in the sky at a given moment in time; the astrological positions are usually given for either noon or midnight depending on the particular ephemeris that is used. In 1554, Johannes Stadius published a well-known work known as Ephemerides novae at auctae that attempted to give accurate planetary positions.
JPL Horizons Ephemeris System - JPL Horizons Ephemeris System provides easy access to key solar system data and flexible production of highly accurate ephemerides for solar system objects.
Sternenbote - The Sternenbote is a monthly astronomy journal, edited by the Austrian astronomical Society (Astroverein) in Vienna. The journal was first published in 1958, and contents include ephemerides of comets and other solar system objects, and observation reports.
Ephemeris time - Ephemeris Time (ET) is a now obsolete time scale used in ephemerides of celestial bodies, in particular the Sun (as observed from the Earth), Moon, planets, and other members of the solar system. This is distinct from Universal Time (UT): the time scale based on the rotation of the Earth around its axis.
