An ephemeris, plural: ephemerides (from the Greek wordφήμερος = ephemeros) is a table of values that gives the positions of astronomical objects in the sky at a given time or times. Astronomy and astrology use different kinds of tables. An astronomical ephemeris may also provide data on astronomical phenomena of interest to astrologers and astronomers such as eclipses and the phases of the Moon.
A modern planetary ephemeris comprises software that generates positions of the planets and often of their satellites, or of asteroids or comets at virtually any time desired by the user. The future ephemerides can be provided because celestial mechanics is an accurate theory.
We choose some ephemerides that can be seen throughout the year 2009 so that everyone can plan to see them. We intend to update these data every year. If you have a telescope or even a simple binoculars you can see a different world at the sky. If you do not have any instrument, use the programs to see the sky like Celestia, Stellarium or Worldwide Telescope.
