The Perseus OB Association is a group of young, massive stars located in the constellation Perseus. This association is part of the larger Perseus constellation and is known for containing several bright stars, including Mirfak and Algol. These stars are relatively close to Earth, at a distance of about 600 light-years, and are thought to have formed from the same molecular cloud. The association is classified as an OB association, which refers to a group of stars that are primarily of spectral types O and B. These stars are characterized by their high temperatures and luminosities, and they play a significant role in the dynamics of their surrounding interstellar medium. The Perseus OB Association is an important area for studying stellar formation and evolution.
