Indian nakshatras

Ardra · Ārdrā

Ardra is a named station in the Indian nakshatra system, a lunar framework distinct from the 88 modern IAU constellations. In common star identifications it corresponds to Betelgeuse in Orion.

Indian nakshatras

History and cultural context

Nakshatra lists occur in early Indian calendrical and ritual astronomy and were used to describe the Moon's progress against the stars. Ardra is traditionally interpreted through the moist or tearful one, associated with Rudra and storms; meanings and ritual associations vary by text, period and regional practice.

How Ardra maps the sky

The nakshatras divide the Moon's sidereal circuit into 27 equal sectors in the dominant scheme, or 28 when Abhijit is inserted. The named stars act as markers, but a mansion is a longitudinal sector rather than a Western connect-the-dots figure.

Interesting facts about Ardra

  • Nakshatra lists occur in early Indian calendrical and ritual astronomy and were used to describe the Moon's progress against the stars.
  • It is commonly located around Betelgeuse in Orion, but that comparison does not make it identical to a modern IAU constellation.
  • The nakshatras divide the Moon's sidereal circuit into 27 equal sectors in the dominant scheme, or 28 when Abhijit is inserted.

How it fits the combined catalogue

The directory stores Ardra as one canonical entry and uses badges for membership and overlap, rather than duplicating it under every official constellation it touches.

Research and cultural care

Use the Sanskrit name and describe this as part of a living Indian calendrical and astrological tradition. Its star marker may lie inside an IAU constellation, but that does not make the mansion equivalent to that constellation.

Star naming is a symbolic gift service. It does not change scientific names or designations maintained by the IAU.
