The term Navagraha denotes the nine celestial bodies which are central to astrological calculations. The sun, the moon, mars, mercury, jupiter, venus, saturn and the two shadow planets Rahu and Ketu constitute the Navagrahas.
Navagraha - the nine planets could be complimentary or inimical to an individual. The navagraha could give harmony or misery to the individual as per its movements.
