NGC 247 is an Intermediate spiral galaxy about 12.2 Mly away in the constellation Cetus. NGC 247 is a member of the Sculptor Group.

[edit] Nearby galaxies and galaxy group information

NGC 247 is one of several galaxies that is gravitationally bound to the Sculptor Galaxy (NGC 253). These galaxies form a small core in the center of the Sculptor Group, which is one of the nearest groups of galaxies to the Milky Way[3]. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core[4][3].
