The scale being logarithmic, this number indicates that its iron content is about 1/250000 that of the Earth's sun.

Discovered by the Hamburg/ESO survey for metal-poor stars, it was probably formed during an age of the universe when the metal content was much lower.

It has been speculated that this star is part of the second generation, born out of the gas clouds which were imbued with elements such as carbon by the primordial Population III stars.

[3] The small amount of metals seen in HE 1327-2326 are believed to have been produced by a supernova event in a first generation star.

Because of this, Ezzeddine et al. argued in 2019 that HE 1327-2326's metal enrichment was due to an aspherical supernova explosion of a 25 M☉ Population III star which enriched the interstellar medium via mass loss through bipolar jets.
