HD 5980 is the brightest star in the Small Magellanic Cloud (SMC) and is located in NGC 346. It has three components all amongst the most luminous stars known: an unusual primary with a Wolf–Rayet spectrum that has produced a luminous blue variable (LBV) eruption; a secondary also a Wolf–Rayet star forming an eclipsing spectroscopic binary; and an O-type supergiant that may not be physically associated.
