Ko te tikanga he paku noa iho, ko tana haurua-iti ko te 70% o tana haurua-nui. Maffei 1 he ahua pouaka (E(b) 3 momo), i te mea ko tona rohe pokapū (radius ≈ 34 pc) he ngoikore i roto i te whakamarama marama i whakaritea ki te ture r1 / 4, te tikanga ko Maffei 1 he momo matua porohita. Ko te ahua o te pouaka me te aroaro o te uara o raro o te uara he mea tino nui ki nga ellipticals nui. Ko nga waahanga o Maffei 1 e tino whakawhirinaki ana ki te roangaru o te marama na te kaha o te pouri o te Milky Way. I roto i te marama puru he 1 <unk> 2 'te whanui i te tata o te infrared ko tana tuaka nui ka tae ki te 23 <unk> neke atu i te 3/4 o te diameter o te Marama. I te tawhiti o te 3 Mpc e rite ana tenei ki te 23 kpc. Ko te rahinga tino kitea o Maffei 1, MV = -20.8, he rite ki tera o te Milky Way.  Pātai: He aha te hautanga o te diameter o te marama e 23?
