In Astrology, Moon signifies calm and peace. While the Sun is related to the soul of an individual, the Moon represents his mind.
More so in Vedic Astrology, Moon is considered to be the most important planet in the birth chart. It moves faster than any of the other plants.
It takes approximately 324 days for the Moon to orbit about the 12 zodiacs, and spends about 27 days in each zodiac sign.
Moon is friendly with the Sun, and planet Mercury. Moon has no enemy planet, and so has a neutral relationship with all other planets; Mars, Jupiter, Venus, Saturn, Rahu, and Ketu. The Moon is the ruler of a zodiac sign, Cancer, and rules the 4th House in the birth chart.
