The Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu are called the Navagraha (9 “Grahas”). Planets are believed to influence the horoscope computed based on time of one\'s birth and subsequently influence the course of life. Each of the planets are believed to move from a star to another during a predefined period and thus sway over an individual\'s fortunes. The Navagrahas, as per Hindu customs, are believed to provide both good and bad effects for any individual and the bad effects are mitigated by prayers.
