HD 73882 is a visual binary system with the components separated by 0.6″ and a combined spectral class of O8. One of stars is an eclipsing binary system. The period of variability is listed as both 2.9199 days and 20.6 days, possibly due to the secondary being a spectroscopic binary star.
The system lies in the constellation of Vela about 2,400 light years away from the Sun and is a member of the open cluster Ruprecht 64.
