Nakshatra is the term for lunar mansion in Hindu astrology. A nakshatra is one of 28 (sometimes also 27)
sectors along the ecliptic. Their names are related to the most prominent asterisms in the respective
sectors. The starting point for the nakshatras is the point on the ecliptic directly opposite to the star
Spica called Chitra in Sanskrit (other slightly different definitions exist). It is called Meshadi or the "start
of Aries". The ecliptic is divided into each of the nakshatras eastwards starting from this point. The
number of nakshatras reflects the number of days in a sidereal month, the width of a nakshatra
traversed by the Moon in about one day. Each nakshatra is further subdivided into four quarters. These
play a role in popular Hindu astrology, where each pada is associated with a syllable, conventionally
chosen as the first syllable of the given name of a child born when the Moon was in the corresponding
The nakshatras of traditional bhartiya astronomy are based on a list of 28 asterisms found in the
Atharvaveda (AVS 19.7) and also in the Shatapatha Brahmana. The first astronomical
text that lists them is the Vedanga Jyotisha.
In classical Hindu scriptures (Mahabharata, Harivamsa), the creation of the Nakshatras is attributed to
Daksha. They are personified as daughters of the deity and as wives of Chandra, the Moon god, or
alternatively the daughters of Kashyapa, the brother of Daksha.
Each of the nakshatras is governed as 'lord' by one of the nine graha in the following sequence: Ketu
(South Lunar Node), Shukra (Venus), Surya (Sun), Chandra (Moon), Mangala (Mars), Rahu (North Lunar
Node), Brihaspati (Jupiter), Shani (Saturn) and Budha (Mercury). This cycle repeats itself three times to
cover all 27 nakshatras. The lord of each nakshatra determines the planetary period known as the
dasha, which is considered of major importance in forecasting the life path of the individual in Hindu
In Vedic Sanskrit, the term nakshatra may refer to any heavenly body or to "the stars" collectively. The
classical concept of a "lunar mansion" is first found in the Atharva Veda, and becomes the primary
meaning of the term in Classical Sanskrit.
