NGC 278 is a spiral galaxy (barred for some authors[3]) in the constellation Cassiopeia. It has a H II nucleus.[4]
Characteristics
NGC 278 is a small and compact high-surface brightness galaxy with high star formation rate taking place in an inner ring with a radius of 2 kiloparsecs, that may have been triggered by the merger with a smaller companion.[5]
