Eta Muscae (η Mus) is a star in the constellation Musca. A multiple star system, the two main components form an eclipsing binary that has a spectral type of B8V and an apparent magnitude of 4.77 that dips by 0.05 magnitude every 2.39 days. Further away are stars of magnitude 7.3 and 10—termed Eta Muscae B and C. It is unclear if these stars are gravitationally bound to the main pair.
