It is interesting to observe that the modern ephemeris lists the planets beginning with the Sun and the Moon and then in order of orbital speed out to Pluto. As Andrew McMahon points out in the Introduction of his publication of Lilly’s Starting Astrology, The ancient astrological cosmological order extends this model further by adding the stars at the highest level and the earth at the lowest level. The understanding that the Sun is actually at the centre of the solar system has been known to astrologers for many centuries, and is reflected in the ancient Chaldean order of the planets (sometimes referred to as the ‘Ptolemaic’ order of the planets) which places the Sun at the centre: Saturn Jupiter Mars Sun Venus Mercury Moon. Sun at the CentreĪstrologers in the 21st century do of course understand that the Sun is actually a star generating enormous amounts of energy fuelled by nuclear reactions at its core, and that the Moon is actually a satellite of the Earth. This distinction must be clearly understood by those who wish to participate in any discussion of astrology. However in current astrological practise the traditional meaning of the word ‘planets’ has not changed, and is still meant to include the lights. In modern astronomy ‘the planets’ have come to represent a distinct category which excludes the lights. The Sun lights up the day sky and the Moon lights up the night sky. The luminaries are also referred to as ‘the lights’. Astrologers have also traditionally used the word ‘planet’ to include ‘the luminaries’, which are the Sun and the Moon.

points of light which appeared to move relative to the other lights which did not seem to move.

In ancient times the cosmic bodies which were seen to wander relative to the backdrop of the fixed stars, which we now understood to include galaxies and other celestial phenomena, were the planets of our solar system. The ‘word’ planet is sourced from the Greek word ‘planētēs’ which means ‘a wanderer’.
