      NGC 247 CHI-1 Bundle

      NGC 247 (Caldwell 62, or the Claw Galaxy) is an intermediate spiral galaxy (although it is sometimes classified as a dwarf spiral galaxy) about 11.1 millions light-years away in the constellation Cetus.

      NGC 247 has an unusually large void on one side of its spiral disk which contains some older, redder stars but no younger, bluer stars.

      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 glaxies to the Milky Way. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core.
