The designations of the three constituents as Pi Scorpii A and B and those of A's components - Pi Scorpii Aa and Ab - derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).

[13] Consequently, the Chinese name for Pi Scorpii itself is 房宿一 (Fáng Xiù yī), "the First Star of Room".

The WGSN decided to attribute proper names to individual stars rather than entire multiple systems.

[11] The fact that Pi Scorpii had two constituents (A and B) remained unknown until 1899, when it was announced by American astronomer Edward Charles Pickering.

[9] A recent analysis[9] of the HR diagram position for the primary star Pi Scorpii A estimates its effective temperature to be 25,230 kelvins with a luminosity of 21,900 Suns, consistent with an isochronal age of 12-14 million years and an estimated mass of 12–13 solar masses.
