NGC 1427 is a low-luminosity elliptical galaxy approximately 71 million light-years away from Earth. It was discovered by John Frederick William Herschel on November 28, 1837. It is located in the Fornax Cluster.[3]

Characteristics

NGC 1427 is an E5 galaxy. It has a diameter of 70 000 light-years. There are 510 globular clusters around the galaxy.

NGC 1427 underwent a merger event within the last 8 billion years.

The now-consumed satellite galaxy contributed 1.5+1.6
−0.7×1010 M☉ to the mass of NGC 1380, which is about one-fourth of its current mass.[3]
