Rahu is not a planet you can point a telescope at. It is the North Node of the Moon, one of two mathematical points where the Moon's orbit crosses the path of the Sun. Classical Jyotish treats Rahu as a shadow planet, a chhaya graha, yet it carries some of the loudest influence in any chart. Where Rahu sits is where you feel restless hunger, the pull to chase something the world tells you matters. This primer gives you the working picture; the linked deep guide takes the same significations much further.

Rahu stands for worldly desire and the ambition that never quite feels satisfied. It rules obsession, the urge to keep reaching for more status, more recognition, more of whatever the sign and house point toward. Because it is the head of the mythic serpent that swallows but cannot digest, Rahu craves without contentment.
It also governs foreign things and unconventional paths: travel abroad, outsider careers, technology, and anything that breaks from tradition. Rahu is the planet of illusion too, so it can inflate a desire until you mistake the craving for the goal. On its better side it delivers sudden gains, unexpected fame, and breakthroughs that arrive faster than any slow, earned reward would.
Nature, motion, and remedy
Rahu is classed as a shadow malefic. It is not evil by default, but its energy is hard to steer, and an afflicted Rahu can bring confusion, anxiety, or fixation. Notably, Rahu is always retrograde in the chart, moving backward through the zodiac alongside its counterpart Ketu, with the two always exactly opposite each other.
The gemstone linked to Rahu is hessonite, the honey-coloured garnet known in India as gomed. Such stones are traditionally worn only after a careful chart reading, never on a hunch, since strengthening a difficult Rahu can amplify the very restlessness you hoped to calm.
