Physical characteristics

NGC 1428 is host to a nuclear star cluster with an estimated mass ranging from 1.4 × 107 {{Cite journal |last1=Lyubenova |first1=Mariya |last2=van den Bosch |first2=Remco C.

The presence of counter-rotating population of stars suggests the occurrence of mergers that occurred in the opposite direction of the rotation of NGC 1428.

The galaxy has a supermassive black hole with an estimated mass of 4.1 × 107 M.{{Cite journal |last1=Arzoumanian |first1=Zaven |last2=Baker |first2=Paul T. |last3=Brazier |first3=Adam |last4=Brook |first4=Paul R. |last5=Burke-Spolaor |first5=Sarah |last6=Becsy |first6=Bence |last7=Charisi |first7=Maria |last8=Chatterjee |first8=Shami |last9=Cordes |first9=James M. |last10=Cornish |first10=Neil J. |last11=Crawford |first11=Fronefield |last12=Cromartie |first12=H.
