VV 47 , also known as Jones-Emberson 1 ( JnEr 1 ) or PK 164 + 31 ° .1 (and erroneously as NGC 2474-75 etc.), is a galactic planetary nebula in the constellation Lynx . It belongs to the apparently larger planetary nebulae and accordingly has a low surface brightness. The white dwarf in the center is possibly a PG-1159 star.
The nebula was discovered by Boris Alexandrovich Voronzow-Veljaminov and independently in 1939 by Rebecca B. Jones and Richard Emberson, who mistakenly identified it with the NGC entry NGC 2474/2475, which actually describes a pair of galaxies a few arc minutes south.
