Rahu and Ketu are known as the lunar nodes in Vedic astrology. Unlike physical planets, they represent mathematical points where the paths of the Sun and Moon intersect.
Rahu
Rahu is traditionally associated with ambition, desire, experimentation, and unfamiliar experiences.
Ketu
Ketu is traditionally associated with detachment, introspection, spirituality, and experiences from the past.
Rahu and Ketu always appear opposite each other in a birth chart, creating an axis between two houses and zodiac signs.
