NGC 78 is a pair of galaxies in the constellation Pisces. [2] NGC 78A, which is the more southern galaxy, is a barred spiral galaxy. [2] NGC 78B, which is the more northern galaxy, is an elliptical galaxy. [4] Although the designations NGC 78A and 78B are used today, the designation NGC 78 was formerly used mainly for the northern galaxy. [5]

Discovery

NGC 78 was discovered no later than 1876 by Carl Frederick Pechüle. [5] It was described as "very faint, small, round" by John Louis Emil Dreyer, the compiler of the New General Catalogue. [5] Because the two galaxies have different recessional velocities, the two galaxies are most likely not interacting. [5]
