NGC 247 is one of several galaxies that is gravitationally bound to the Silver Coin Galaxy NGC 253. It is an intermediate spiral galaxy (although it is sometimes classified as a dwarf spiral galaxy) about 11.1 Mly away in the constellation Cetus. The galaxy displays an obvious void on the north side of its spiral disk, but the exact nature and cause of this feature is not clear. The void contains some older, redder stars but no younger, bluer stars.

The string of four galaxies just below and right of NGC 247 is known as Burbidge's Chain. These galaxies are about 300 million light-years distant. Deep images reveal that the two bottom-most galaxies in the chain are apparently interacting, joined by a faint bridge of material. This bridge can just be seen in this photograph.
