NGC 1332 is an almost edge-on elliptical galaxy located in constellation of Eridanus. Situated about 70 million light years away, it is a member of the Eridanus cluster of galaxies, a cluster of about 200 galaxies. It is also the brightest member of the NGC 1332 Group. It was discovered by William Herschel on 9 December 1784.
NGC 1332 has a Hubble classification of E, which indicates it is an elliptical galaxy. It is moving away from the Milky Way at a rate of 1,553 km/s. Its size on the night sky is 4.5' x 1.4' which is proportional to its real size of 92 000 ly.[citation needed]
NGC 1332 is an early-type 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.[3]
One supernova has been observed in NGC 1332: SN 1982E (type unknown, mag. 14).[4]
