NGC 4945 is a spiral galaxy in the constellation Centaurus, and near the bright star, Zeta Centauri. The galaxy was discovered by [3 ] James Dunlop in 1826. It is thought to be similar to the Milky Way Galaxy, although X-ray observations show that NGC 4945 has an unusual energetic Seyfert 2 nucleus that might house a large black hole. [4 ]
Galaxy group [ edit ]
NGC 4945 one of the brightest galaxies of the
Centaurus A/M83 Group, a large, nearby group of galaxies. The galaxy is the second brightest galaxy in the subgroup centered on Centaurus A. [2 ] [5 ]
