Simmakh is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Sumerian, from SIM.MAḪ. It is the name of the star d Psc (HIP 1645) in constellation Pisces.
Concordance, Etymology, History

Babylonian constellation that has undergone massive transformations: the original Giant Swallow was turned into a Swallow-Fish and into two fish connected with a ribbon. It is located in the area of modern Pisces. Alternative Mesopotamian terms are mulŠIM.MAḪ (𒀯𒋆𒈤) and (mul)Šinūnūtu.
The characteristic folked tail of a swallow actually matches the pattern of stars in the sky very well; so it is very likely the original image seen in the asterism that is now considered a V-shaped ribbon.
The transformation of the constellation of The Swallow (see SIM.MAḪ) in ancient Mesopotamia is characterised by the original image of a Giant Swallow which must be located in Cetus, as its tails are imagined in the ribbon of Pisces, to a later version of a much smaller bird (swallow) whose body is roughly in the southern fish-ellipse of Pisces. The second image is reconstructed from coordinates given in Late Babylonian texts, e.g. the normal star list in which reads "DUR sim.ma", "Swallow Ribbon" [Roughton-Steele-Walker 2004[1], 551:21′, 553], suggesting a bird connected to a fish in the northern fish-ellipse. Such an image of a bird and a fish connected by a V-shaped ribbon is preserved on seals in Uruk.
Yet earlier texts like MUL.APIN only list a Swallow and no fish in this area. The stars of Anu (no. 2), MUL.APIN I i 41 = (Anu 2right)[2]:
- MUL ša2 ina IGI-it mulAŠ.IKU GUB-zu mulŠi-nu-nu-tu4
- "The star that stands before the Field, the Swallow"
Mythology
IAU Working Group on Star Names
The name was suggested to the IAU WGSN in 2023. It was adopted for a star south of the Pegasus square which matches both image reconstructions: the earlier large swallow (at the tip of its tail) and the late small swallow (in the body/head).
The name was adopted by the IAU WGSN in September 2026.
