It belongs to the apparently larger planetary nebulae and has a correspondingly low surface brightness. The white dwarf in the center is possibly a PG-1159 star.
The nebula was discovered by Boris Alexandrovich Voronzow-Velyaminov and independently in 1939 by Rebecca B. Jones and Richard Emberson, who mistakenly identified it with NGC entry NGC 2474/2475, which in fact describes a pair of galaxies a few minutes of arc to the south.
