NGC 247 is an Intermediate 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 was proved to be wrong. NGC 247 is a member of the Sculptor Group
.
(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
. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core.
Intermediate spiral galaxy
An intermediate spiral galaxy is a galaxy that is in between the classifications of a barred spiral galaxy and an unbarred spiral galaxy. It is designated as SAB in the galaxy morphological classification scheme.-Grades:...
