Shani or Saturn is the most fiery planet, according to Vedic astrology. Saturn is the slowest moving planet in the solar system. Due to this, it is a cold, barren, dry, secretive planet and its effects are felt with greater intensity and for longer periods than any other planet. It is said that Shani planet is favorable to all those people born under signs owned by Venus. On the other hand, Saturn is evil to those who are born under signs owned by Mercury.
