Ninnisig is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Sumerian. It is the name of the star θ Lyr in constellation Lyra.

Concordance, Etymology, History

Nin-nisig (see Kurtik n40)[1] and Erragal are a couple of ancient Mesopotamian gods. Ninnisig is the butcher of Enlil’s palace Ekur, wife of Erragal. Her name is usually translated as "Lady Greenery" or "Lady Greens."[2] They are attested as two stars in MUL.APIN, the oldest astronomical known compendium (dating between 1350 and 1150 BCE)[3]:


MUL.APIN (I i 27)[3]

  • DIŠ 2 MULmeš ša2 EGIR-šu2 GUBmeš-zu dNin-SAR u dEr3-ra-gal
  • The two stars which stand behind it [the Goat]: Nin-nisig and Erragal.

These two stars are identified with η + θ Lyrae (e.g bei Weidner 1957-59[4]).
