Boat and Decans in tomb of Karakhamun  (CC BY Elena Pischikova and Miguel A. Molinero, in Lull 2018).

Kenemu (knmw), Crew, is an Egyptian constellation of three stars ρ1 Sgr = 44 Sgr.[1][2] (Stars of) Kenmu, 17th decan in Egyptian astral science, has its heliacal rise in month Peret, represented by a small group of stars around ρ1 Sgr.

Concordance, Etymology, History

The Boat and its Crew, Wja and Kenemu, in the Book of Nut (Lull 2018)

Origin of Constellation

Decans of Wja+Knmw in the astronomical ceiling of Esna (Lull 2018).

Kenemu is the name of a decan (possibly form by several stars as its name indicate, the Crew) of the constellation Wia, The Boat, which is formed by several stars expanding from before the Red of the Prow (Antares) to the end of Sagittarius. It is sailing the Milky Way.  

identifications of Decans in Lull (2018)

Lull (2018)[1] dedicates an entire research paper to the discussion, cultural embedding and astronomical identification of Wia, The Boat, with Knmw, The Crew. He concludes on the identification of Knmw with the area between the stars ρ1 Sgr (44 Sgr).

Previous Identification: Leitz (1995, 91)[3] reads knm and translates The Dark One, which he interprets as a reference to fainter stars. His identification with λ Aql is refuted by Belmonte and Lull (2023),[2] who also adopt another reading of the original hieroglyphs.

IAU WGSN star name discussion

The name was proposed to WGSN in 2025. As Kenemu means something as "crew", we are not sure if it would be appropriate for a single star. Juan Belmonte suggests to look for any pair of closing stars or a star which is multiple (not to the naked eye) in the area east of Kaus Australis, as in that case, it may suit. Yet, Belmonte and Lull (2023) and Lull (2018) both identify ρ1 Sgr at 3.93 mag in V.

In 2026, the name "Kenemu" was proposed for the star ρ1 Sgr (Rho1 Sagittarii, 44 Sgr, HR 7340, HD 181577, HIP 95168), a spectral type A9IV star with apparent magnitude V=3.92 that lies 40 parsecs away. The star is a Delta Scuti variable star that varies at the ~0.04 magnitude level on a timescale of ~1.2 hours. The star has a mass approximately 1.9x that of the Sun, and a luminosity of approximately 31x the Sun, placing it about ~1.5 magnitudes brighter than the main sequence, and making it a post-main sequence star.
