    NGC 3199  is an asymmetric emission nebula located around the runaway Wolf-Rayet star WR18. Regions near the arc-shaped shock front contain nitrogen-rich gas, which is enhanced by WR 18's stellar wind  Wolf-Rayet stars are the exposed cores of massive hot stars. They are not assigned to any of the usual spectral classes, but are classified into their own type.
