The planets keep revolving and the revolution of each planet has significant values to individual lives on earth. Some branches of horoscope astrology lay emphasis on the movement of Sun while others hold the Moon as the focal point. Those which hold the Sun as the focal point call their system as the Solar system while the Lunar System represents those considering the Moon as the focal point. The time of birth and place of birth are important considerations in horoscope astrology.

A minor difference in the time of birth is believed to impact horoscope astrology substantially. Precise details on the other hand, can produce a very reliable horoscope.
