NGC 10
Spiral galaxy in the constellation Sculptor
From Wikipedia, the free encyclopedia
NGC 10 is a spiral galaxy located in the southern constellation of Sculptor. It was discovered by John Herschel on 25 September 1834.[8] The galaxy is located at a distance of 346 Mly from the Sun.[3] Its morphological classification in the De Vaucouleurs system is SAB(rs)bc,[4] where the 'SAB' denotes a weak-barred spiral, '(rs)' indicates a slight ring-like structure, and 'bc' means the spiral arms are moderately to loosely wound.[9] Paturel et al. (2003) assigned this galaxy a classification of SBbc, indicating a barred spiral galaxy.[5]
