NGC 247

From Wikipedia, the free encyclopedia

"NGC 247 (also known as Caldwell 62 and commonly known as the Claw Galaxy) is an intermediate spiral galaxy (although it is sometimes classified as a dwarf spiral galaxy) about 11.1 Mly away in the constellation Cetus. This distance was confirmed in late February 2011. Previous measurements showed that the galaxy was about 12.2 Mly away, but this was proved to be wrong] NGC 247 is a member of the Sculptor Group and is 70 000 light years in diameter.

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."
