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]
Structure
Structurally, NGC 2841 is a giant spiral galaxy with properties similar to those of the Andromeda Galaxy.[2] It is a prototypical flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous.[3]
NGC 2841 is also noted for its large population of young blue stars, and few H II regions.[4]

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.[5]
