NGC 321 is an elliptical galaxy[3] located in the constellation Cetus. It was discovered on September 27, 1864, by the astronomer Albert Marth.[4] Measurements of its redshift put it at a distance of about 217.4 ± 15.4 megalight-years (66.67 ± 4.73 Mpc), assuming a Hubble constant of H0 = 67.8 km/sec/Mpc.[5]

It was the location of the planet Eminiar VII in the original series Star Trek episode "A Taste of Armageddon" (where it was incorrectly identified as a star cluster).[citation needed]
