Alcyone ephemeris is an accurate and fast astronomial ephemeris calculator covering the period 3000 BC to AD 3500. Itcalculates heliocentric, geocentric, and topocentric positions of the Sun (Earth), Moon, and planets in ecliptical, equatorial, and horizontalcoordinates, with optional corrections for parallax and refraction; rectangular coordinates, velocity, acceleration, apparent diameter,magnitude, phase, lunar libration, orbital elements, differences...

saturn's ring system makes the planet one of the most beautiful objects in the solar system. It was difficult to reflect it's beautyby computer simulation, but after a lot of experiments on cutting edge of modern 3d technologyies we have reached the target of reallyphoto-realistic simulated animation of this spectacular scene. Ring's shadows, incredible cosmic sunrises, atmospheric refraction and manyother features makes the each single frame of endless smooth animation...
