HD 91324 is a binary F9V star in the constellation Vela. Its apparent magnitude is 4.89. 2MASS J10313234–5338010 was found to be a possible companion to HD 91324 through a proper motion study combining data from the Two Micron All-Sky Survey and the WISE space telescope. The projected separation of the two stars is 6700 AU. Proper motion measurements for the two stars is almost identical making HD 91324 a binary star. The photometry of 2MASS J10313234–5338010 is consistent with a red dwarf of spectral type M5 or M6[2]
