From Wikipedia, the free encyclopedia
Perseus OB1 is an
OB association in the
Northern Celestial Hemisphere in the constellation Perseus. It is centered around the
double cluster (
NGC 869 and
NGC 884 ),
[6] and has lent its name to the
Perseus Arm of the
Milky Way .
[8] The brightest member of the association is the
blue supergiant
9 Persei .
