Name and etymology

  • This star, together with δ Per, ψ Per, σ Per, α Per and γ Per has been called the Segment of Perseus..
  • Jim Kaler expressed his doubts about this star having any proper name, not considering "Miram" reliable, after taking into account Richard Hinckley Allen's source stating it has no proper name.
  • In Chinese, 天船 (Tiān Chuán), meaning Celestial Boat, refers to an asterism consisting of η Persei, γ Persei, α Persei, ψ Persei, δ Persei, 48 Persei, μ Persei and HD 27084. Consequently, η Persei itself is known as 天船一 (Tiān Chuán yī, English: the First Star of Celestial Boat.)
