HR 5967
Scientific overview
HR 5967 is a blue giant in the constellation Lupus (Lupi), lying about 399.7 light-years from Earth.
Class B. Hot, blue-white stars. Massive and luminous, they often light up the regions where they form. Such stars have surface temperatures around 10,000–30,000 K and appear blue-white to the eye.
