Meaning
Ardra means "the moist one" and is Betelgeuse, the bright red star at Orion's shoulder.
Its god is Rudra of the storms, and modern readings follow the weather: the storm that clears the air, intense feeling, sharp perception, upheaval and the freshness after the rain. The tradition reads Ardra as a place of turbulence that ends in renewal.
Rahu is its lord in the Vimshottari order, so a Moon in Ardra begins the reckoning in Rahu's eighteen-year period, as it does for the sample person on our system page, born with the Moon in Ardra's third pada.
Deity and emblem
Rudra is Ardra's deity in the Taittiriya Samhita and today.
Here the modern emblem and the old figure part company. Modern books give a teardrop; Burgess and Whitney's medieval lists give a gem. Our chart shows the teardrop labelled as the modern tradition's symbol, with the gem beside it as the figure of the medieval lists.
In the chart
Ardra runs from 6°40′ Mithuna to 20°00′ Mithuna of the sidereal zodiac, the sixth of 27 equal parts of 13°20′. It lies wholly within Mithuna (Gemini). Its four padas of 3°20′ fall in the navamsas of Dhanu, Makara, Kumbha and Meena, so a graha in its first pada stands in Dhanu in the D9.
Its Vimshottari lord is Rahu, whose period is eighteen years. When the Moon stands here at birth, the reckoning opens in Rahu's period and counts only the part still to run, in proportion to the part of Ardra the Moon has yet to cross. In 2026 the same stretch of sky is about 0°53′ Cancer to 14°13′ Cancer in the tropical zodiac, by the Lahiri measure; another ayanamsa moves the edges, and a Moon or lagna within a few minutes of arc of an edge can fall in the neighbouring nakshatra in another tool.

How the schools read it
- The Vedic lists (Taittiriya Samhita iv.4.10, Keith 1914)
- Rudra, as today; the Taittiriya list begins with Krittika.
- The medieval lists (Burgess and Whitney, 1860)
- The figure of the asterism: a gem, after the Ratnamala and the Muhurta Chintamani.
- Modern Jyotisha
- Intensity, perception, upheaval and the renewal that follows; its symbol: teardrop.
- The 28-nakshatra scheme
- Abhijit, in the stars of Lyra, stands between Uttara Ashadha and Shravana in the older lists; the equal division into 27 leaves it out.
- Western sidereal (Fagan-Bradley)
- The same 27 divisions, about 0°53′ further on than Lahiri's; Western siderealists rarely use them.
- EsoTerrier
- Our chart's text for a Moon here: "Ardra is ruled by Rahu and named for moisture, carrying the energy of Rudra's storms that break and then renew. Its nature is intense, perceptive and transformative, and allowing difficult feelings to clear like rain after a storm can bring fresh clarity." Our words.
Claims about it
-
Ardra's deity and symbol are one fixed set handed down from the Vedas.
disputedWhat the record shows: The deity, Rudra, is the same in the Taittiriya Samhita (iv.4.10) and today, but five other nakshatras have different deities in different Vedic lists. The symbol, teardrop, is the modern tradition's and has no dated source we found; the medieval lists give a gem.
-
The nakshatra is a constellation, 13°20′ wide.
falseWhat the record shows: The nakshatras began as star groups of unequal size, 28 in the Atharvaveda with Abhijit. The equal division into 27 parts of 13°20′ is a later convention; the name points at stars, the division is arithmetic.
-
The Moon's nakshatra reveals the hidden depths of the mind.
unverifiedWhat the record shows: In the tradition the janma nakshatra starts the dasha, gives the name syllable and is used for chosen times and matching; the psychological language is modern and Western.
