NGC 45 is a low surface brightness spiral galaxy in the constellation of Cetus. It was discovered on 11 November 1835 by the English astronomer John Herschel. In the sky, it is located near the magnitude 6.8 star HD 941.
NGC 45 has no clear defined spiral arms like the Milky Way galaxy. Unlike the Milky Way, the center bar nucleus is also very small and distorted. NGC 45 thus does not have a galactic habitable zone like the Milky Way. For the Milky Way, the galactic habitable zone is commonly believed to be an annulus with an outer radius of about 10 kiloparsecs and an inner radius close to the Galactic Center, both of which lack hard boundaries.
