The sun and the moon are called planets, even though we know that they are not ... as in astrology uses the geocentric ... with the world at the center of the universe and everything that surrounds it.
Sun and Moon Luminaries are called ... diurnal luminary luminary the sun and the moon at night. The Earth
therefore not considered as a planet, but it is the central point of reference, as it is considered a wanderer in the sky.
The ancient astrologers only knew the planets visible to the naked eye ... trained eye to say ... because I can not see past the sun, moon and Venus :)
seven planets were known in the ancient world:
Sun, Moon, Mercury , Venus, Mars , Jupiter and Saturn ... and are often associated with the seven chakras in the West were in fact called a planet.
octaves above are Uranus, Neptune and Pluto, and later discovered planets represent the higher vibration of three traditional planets, since it does not belong to the seven initial.
Uranus is the higher octave of Mercury (intellect, logical and practical -> intuition, higher knowledge and synthesis)
Neptune is the higher octave of Venus (love sensual -> mystical love, love for all)
Pluto is the higher octave of Mars (action, dynamic energy outside - the inner strength to live inner transmutation)
