WR 102 is a Wolf-Rayet star in the constellation of Sagittarius.
The star has a mass 16 times that of our sun and is 200,000 degrees hotter than our sun, shining at 100,000 times the brightness of our sun.
A study in 2016 concluded that the morphology was typical for hydrogen-free WN6 stars as is the nebula surrounding it.
The nebula was formed by interaction of fast stellar wind with matter ejected from WR 102.
Calculations are that WR 102 will go supernova within 1500 years.
