Alcyone Ephemeris is an accurate and fast astronomical ephemeris calculator covering the period 3000 BC to AD 3000. It calculates heliocentric, geocentric, and topocentric positions of the Sun (Earth), Moon, planets and fixed stars in ecliptical, equatorial, and horizontal coordinates (including angular differences between two bodies), with optional corrections for parallax and refraction; rectangular coordinates, velocity, apparent diameter, magnitude, phase, lunar libration, orbital elements, differences for all of these, and more. In addition Alcyone Ephemeris offers a wealth of functionality: plotting ephemeris data, searching for specific values, scripting to write programs for more complex computations, saving as HTML or Excel files to export output to spreadsheets, word processors and web pages, and printing. The ephemeris...

Planet's Orbits (for Windows 98/ME/2000/XP) is an accurate digital orrery with a wealth of functionality. The program uses the DE404 ephemeris (accurate for dates between 2000 B.C. and 6000 AD) for the calculation of planetary (except Pluto) and lunar positions. The calculation of the positions of the satellites of Jupiter, Saturn, and Uranus is done by the various analytic theories given in the Explanatory Supplement to the Astronomial Almanac (1992).The positions of the other objects (asteroids, comets) are calculated by it's osculating orbital elements. Therefore the positions of these objects are accurate only for a small period of time.The version 1.7. shows the positions and trajectories of various spacecrafts.The most noteworthy functions are date specification (past, future), 2D/3D orbital animation and custom zoom, orbits of...

Planetâs Visibility presents a 3-color graph that shows when a planet, the moon or the sun is visible during any year from 3000 BC to AD 6000 at any location on the earth. The vertical axis marks the months of the year, the horizontal axis marks the hours of the day. The three colors create a contour map effect that indicates the visibility. In addition times of solar and lunar eclipses are marked and the dates of heliacal phenomena are computed.
