Each planet in our solar system affects an element of your personality.
Rabbi Philip S. Berg describes the influence of the planets in Kabbalistic Astrology Made Easy:
"Since each planet has its own speed and orbit pattern, the influence manifested by the combination of the various magnetic fields is unique at any given point in time. Human beings react to these magnetic fields; even a fetus in the womb receives signals from the planets and constellations...These magnetic signals are none other than the physical expressions of the inner energy-intelligence of heavenly bodies. The necessary spiritual dispositions and character traits of the child are revealed by the position and dynamic interaction of the heavenly bodies at the moment of birth."
