Notes

Identified as an asymmetric planetary nebula with a binary central star (Frew et al., 2013), the symbiotic classification is deemed improbable according to their findings. Exhibiting variability with a period of 21 days, this object has been detected in X-rays, UV, and IR. The dynamic age is estimated at 19,500 years, with a distance of 760 pc as inferred by Ali et al. (2012). Further confirming its non-symbiotic nature, Merc et al. (2021) conducted a spectral analysis of the object.
