Ketu and Rahu are two planetary points that crucially determine a person's fortune according to vedic astrology. Different positions of Rahu and Ketu could tell a great deal about future as well. These points happen to be at geometric distance of one hundred and eighty degree.
The astrolger of vedic astrology is known as Jyotishi. A Jyotishi observes various planetary movements in order to make predictions. Like western astrology, vedic astrology also offers it's dailyhoroscope.
Vedic astrology strongly believes that fate of a person keeps changing with his/her actions or karma. Changing planetary positions reflect the same thing.
Planets existing in the solar system are termed as navgarha and along with rahu and ketu they are examined to make astrological statements.
The astrology observes movements of various astrological stars on imaginary path. Usually there are two groups of stars in this astrology. Stars are in twenty six clusters and each cluster has a name.
