The object exhibits highly collimated bipolar outflows, as reported by Torres-Peimbert et al. (2010), who also suggested its possible symbiotic nature. The object bears similarities to M2-9 and is additionally classified as a symbiotic star candidate in the HASH Database of PNe (Parker et al., 2016).
