To the Greeks and the other earliest astronomers, this group consisted of the five planets visible to the naked eye and excluded Earth.
Although strictly, the term planet applied only to those five objects, the term was latterly broadened, particularly in the Middle Ages, to include the Sun and the Moon (sometimes referred to as "Lights"), making a total of seven planets. To ancient astrologers, the planets represented the will of the gods and their direct influence upon human affairs.
Others hold that the planets have no direct influence in themselves, but are mirrors of basic organizing principles in the universe.
In other words, the basic patterns of the universe repeat themselves everywhere, in fractal-like fashion, and "as above, so below".
They are the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn.Sometimes, the Sun and Moon were referred to as "the lights" or the "luminaries".Vesta and Uranus can also just be seen with the naked eye, though no ancient culture appears to have taken note of them.Listed below are the specific meanings and domains associated with the astrological planets since ancient times, with the main focus on the Western astrological tradition.The planets in Hindu astrology are known as the Navagraha or "nine realms".Also of interest is the conflation of the Roman god with a similar Greek god.
