WR 120 is a binary containing two Wolf-Rayet stars in the constellation of Scutum, around 10,000 light years away. The primary is a hydrogen-free weak-lined WN7 star, the secondary is a hydrogen-free WN3 or 4 star, and the system is a possible member of the cluster Dolidze 33.^[8] From our point of view, WR 120 is reddened by 4.82 magnitudes, and it has the variable designation of V462 Scuti.^[9]
