NGC 2998 is a barred spiral galaxy located in the constellation Ursa Major. [5] It is 195 million light-years (59.7 megaparsecs) away from the Earth. [3] It is an intermediate spiral galaxy. [5] Its stellar mass is about that of the Milky Way. [6]

NGC 2998 is a member of the eponymous NGC 2998 group, a relatively dense galaxy group which also includes NGC 3002, NGC 3005, NGC 3006, NGC 3008 and a few others. [7] [6]
