Hen 3-1333 is a planetary nebula in the constellation Altar , which was cataloged by Karl Gordon Henize in 1976.
Inside the nebula lies the Wolf-Rayet star V837 Arae with about 60% of the solar mass and a temperature of 30,000 Kelvin . The star is surrounded by a disk of dust that, from Earth's perspective, causes a periodic fluctuation in the star's apparent brightness.
