It has been established over the ages that the planets, right up there in the solar system have a formidable influence on human life. The thinking and behavior patterns of human beings, and that the turn of events in his/her life is largely shaped by the stars in our galaxy.
The Sun and the planets have the greatest and most immediate influence on the Earth's atmosphere and environment because the Earth is a part of the solar system.
