It is a yellow-white supergiant ranging between spectral types F7Ib and G2Ib,[31] located around 2037light-years away.[32] S Muscae is likewise a classical Cepheid, a yellow-white supergiant ranging between spectral types F6Ib and G0Ib and magnitudes 5.89 to 6.49 over a period of 9.66days.[33] A luminous star around 5.9times as massive as the Sun, it is a binary star with a blue-white main-sequence star companion likely to be of spectral type B3V to B5V with a mass of just over 5solar masses,[34] one of the hottest and brightest companions of a cepheid known. The two stars orbit each other every 505days.[35]
