HD 32667 is a hierarchical triple star system located about 192 light-years (59 pc) away in the southern constellation of Lepus. The brightest of the three components, and the only one visible, is a hot white subgiant star. With an apparent magnitude of 5.582, it is faintly visible by the naked eye in dark skies. In Chinese astronomy, the star was given the name Jiǔ yóu zēng qī (Chinese: 九斿增七; lit. 'Nine flag addition seven'),[6] meaning it was the seventh star added to the asterism Jiǔ yóu (九斿, "Imperial Military Flag") in the Net mansion, when the star chart Yixiang Kaocheng [zh] (仪象考成) was compiled between 1744 and 1752.[7][8]

The star is listed in the Catalogue of Ap, HgMn and Am Stars as an A2-type Am star designated Renson 8370,[5] although astronomer Dorrit Hoffleit suggested the contrary, classing it as an A3 weak-line star.[9]
