NGC 247 (also known as Caldwell 62 and commonly known as the Claw Galaxy12.2 Mly away, but this was proved to be wrong.[4] NGC 247 is a member of the Sculptor Group, and is 70 000 light years in diameter. [5]
NGC 247 has an unusually large void on one side of its spiral disk. This void contains some older, redder stars but no younger, bluer stars.[6]
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.[7] Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core.[7][8]
