BAT99-98 is a Wolf–Rayet star located in the Large Magellanic Cloud, in NGC 2070 near the R136 cluster in the Tarantula Nebula (30 Doradus). At estimates of and , it is one of the most massive known stars, and close to one of the most luminous stars currently known.
==Observations== A 1978 survey carried out by Jorge Melnick covered the 30 Doradus region and found six new Wolf–Rayet (WR) stars, all belonging to the WN sequence. The survey observed stars that were above apparent magnitude 14 and within 2 arcminutes of the centre of the 30 Doradus nebula, and the star now known as BAT9998 was labelled as star J. It was found to have a magnitude of 13.5 and a spectral type of WN5.
