HD 330075 is a 9th magnitude star approximately 164 light-years away in the southern constellation of Norma. Like our Sun, it is a yellow dwarf (spectral type G5). However, it is slightly cooler and less luminous. Due to its distance, it is rather dim and visible only with telescope or powerful binoculars.[1]

In 2004, the discovery of a hot Jupiter planet orbiting the star was announced. This is the first planet discovered by the HARPS spectrograph.[2]
