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]

  • NGC 278 is in the northern constellation of Cassiopeia.[6]
