Holmberg IX is a dwarf irregular galaxy and a satellite galaxy of M81. The galaxy is named after Erik Holmberg who first described it. Based on the observed age distribution of stars it contains it is thought to have formed within the last 200 Myr making it the youngest nearby galaxy.[2] It is also home to one of two newly discovered yellow supergiant eclipsing binary systems.[3][4]
