Other parties contributed PostScript graphics, and integrated ephemeris files for minor planetary objects. Astrolog has been ported to many different platforms, where versions exist for Unix, MS-DOS, Microsoft Windows, Macintosh, OS/2, and Amiga, among others. [4] [5] Astrolog has also been distributed as sample packages with versions of SUSE ...
Software libraries exist to aid in the development of astronomical software. These libraries can also be leveraged for use in astrological projects. One such tool is Swiss Ephemeris, which is an astronomical almanac developed by Astrodienst AG, Switzerland, the makers of Astrolog. It is widely used for calculating the positions of planets ...
XEphem started as a Unix and Motif conversion of the IBM PC-based ephem.It was initially released in December 1993 with version 2.5. [citation needed] Its commercial edition was discontinued in 2016; the free version continued to be offered as proprietary software. [3]
Raphael's Ephemeris was issued as a separate publication after Smith’s death, whilst others adopted and continued with the name 'Raphael'. The "second Raphael" was John Palmer (1807–1837), a former student of Smith's, who edited Raphael's Sanctuary of the Astral Art in 1834; the third was a Mr. Medhurst, the editor of the Prophetic ...
In astronomy and celestial navigation, an ephemeris (/ ɪ ˈ f ɛ m ər ɪ s /; pl. ephemerides / ˌ ɛ f ə ˈ m ɛr ɪ ˌ d iː z /; from Latin ephemeris 'diary', from Ancient Greek ἐφημερίς (ephēmerís) 'diary, journal') [1] [2] [3] is a book with tables that gives the trajectory of naturally occurring astronomical objects and artificial satellites in the sky, i.e., the position ...
Newcomb's Tables of the Sun (full title Tables of the Motion of the Earth on its Axis and Around the Sun) [a] is a work by the American astronomer and mathematician Simon Newcomb, published in volume VI of the serial publication Astronomical Papers Prepared for the Use of the American Ephemeris and Nautical Almanac.

Two sample pages of the 2002 Nautical Almanac. The Nautical Almanac has been the familiar name for a series of official British almanacs published under various titles since the first issue of The Nautical Almanac and Astronomical Ephemeris, for 1767: [1] this was the first nautical almanac to contain data dedicated to the convenient determination of longitude at sea.
A first application of this concept of dynamical time was the definition of the ephemeris time scale (ET). [ 1 ] [ 2 ] In the late 19th century it was suspected, and in the early 20th century it was established, that the rotation of the Earth ( i.e. the length of the day ) was both irregular on short time scales, and was slowing down on longer ...
