NGC 1400 is an elliptical galaxy in the constellation Eridanus. At a distance of 65 million light-years from Earth, it was discovered by John Herschel in 1786. It is a member of the NGC 1407 group, whose brightest member is NGC 1407. The NGC 1407 group is part of the Eridanus Cluster, a cluster of 200 galaxies.

NGC 1400 is an early-type E0 galaxy. Despite their name, early-type galaxies are much older than spiral galaxies, and mostly comprise old, red-colored stars. Very little star formation occurs in these galaxies; the lack of star formation in elliptical galaxies appears to start at the center and then slowly propagates outward.[4]
NGC 1400 has had star formation in the past, which was caused by NGC 1400 falling into the NGC 1407 group.[5]
One supernova has been observed in NGC 1400: SN 2021hcz (type Ia, mag. 15.4).[6]
