The "Golden Orb of Day" was a term used by the Shelak Tribe during the Aeon of Strife to describe the star that Aiur orbits. Protoss biology evolved to draw nourishment from its light.[1]

The star is orbited by at least four planets, with Aiur being at least the third planet from the star[2] and the outermost planet, Aleun.[3]
