Rahu is one of the nine major astronomical bodies (navagraha) in Indian texts. Unlike the other eight, Rahu is not a real astronomical body but a shadow entity, one that causes eclipses and is the king of meteors.[1]

Rahu is usually paired with Ketu. The time of day considered to be under the influence of Rahu is called Rahu kala and is considered inauspicious.[2]

Rahu is mentioned in Buddhist, Hindu and Jain texts.[1][3][4] Rahu is also found in astrology and horoscopes
