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]
