Den har en kombinerad skenbar magnitud av ca 7,27 och kräver åtminstone en stark handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 1,2 mas, beräknas den befinna sig på ett avstånd på ca >10 000 ljusår (ca 3 200 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 15 km/s.liocentrisk radialhastighet på ca 15 km/s.
, HD 93403 is a spectroscopic binary contain … HD 93403 is a spectroscopic binary containing two highly luminous hot blue stars. It is 10,000 light years away in the Carina Nebula in the constellation Carina. It appears to have spectral type O5.5III, but this is composed of two spectra from a blue supergiant and blue main sequence star of spectral type O5.5I and O7V respectively. The two stars orbit every 15 days with a separation that varies from 93 R☉ to 149 R☉. The binary is shedding mass at the high rate of 0.0005 M☉ per year. HD 93403 exhibits the Struve-Sahade effect, where the strength of the spectral lines of the individual components varies during the orbit. It also has colliding stellar winds that produce variable x-ray and non-thermal radio emission.able x-ray and non-thermal radio emission.
