NGC 246

NGC 246, a planetary nebula in the constellation of Cetus is about 1600 light-years from Earth. NGC 246 is also known as the Skull Nebula. The progenitor is the white dwarf seen at the center of the nebula. At a distance of 1900 AU it is orbited by another star. In 2014 using ESO’s VLT a dim red dwarf was discovered to be orbiting the white dwarf at a distance of 500 AU. This makes NGC 246 the first known planetary nebula with a triplet system at its center.
