Shatabhisha is nakshatra number 24 of the 27 lunar mansions in Vedic astrology, spanning 306.67° of the zodiac in 13°20' steps. Its planetary lord is Rahu and its presiding deity is Varuna.
The Moon's position in Shatabhisha at birth shapes the Vimshottari Mahadasha sequence — a Shatabhisha birth begins life in the Rahu mahadasha, with the balance of that period decided by how far the Moon had travelled through the nakshatra.
