Planetary Positions
"This page gives the geocentric (earth-centered) positions of the Sun, Moon and the planets. A list of astrological conjunctions is attached. The right ascension is correct to within a couple of minutes. Some of the declinations have reversed signs; this is a known bug (however these are not used in conventional astrology). The position of Pluto will be off by a bit more than the other planets, but accurate to within a degree or two. The algorithm does not take into account interplanetary gravitational interactions; it uses the current orbital characteristics of each planet and interpolates from a known set of values. Hence, the further back or forward in time you set the date to, the less accurate the positions will be; they will be more accurate the closer they are to 1 January 1980. This algorithm does not take into account the precession of the equinox..."
