NGC 2841 is an inclined unbarred spiral galaxy in the constellation Ursa Major. Initially thought to be about 30 million light years distant, a 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined that it was approximately 14.1 megaparsecs or 46 million light years distant.^[2] Structurally, NGC 2841 is noted for its large population of young blue stars, and few H II regions. ^[3]

LINER emission

NGC 2841 contains a low-ionization nuclear emission-line region (LINER), a type of region that is characterized by spectral line emission from weakly ionized atoms.^[4]
