NGC 78

NGC 78 is a lenticular galaxy located in the constellation Pisces. It is approximately 275 million light-years away from Earth. NGC 78 is designated as an S0 galaxy, indicating it possesses a disk and a central bulge but lacks prominent spiral arms.

NGC 78 is part of a galaxy pair with NGC 78A (also known as PGC 1306 or MCG 0-2-6). While visually close, whether they are gravitationally interacting is uncertain, with some studies suggesting they are merely a line-of-sight alignment. NGC 78A is a more irregular galaxy compared to NGC 78.

The galaxy was discovered on November 17, 1784, by the astronomer William Herschel. It is a relatively faint object, requiring a moderately sized telescope to observe.

Further research on NGC 78 involves studying its stellar population, its distance and redshift, and its possible interaction with NGC 78A to understand its formation and evolution.
