NGC 1309 is a spiral galaxy of Hubble type Sbc in the constellation Eridanus south of the ecliptic . It is estimated to be 93 million light-years from the Milky Way and about 60,000 ly in diameter. It is one of over 200 galaxies that make up the Eridanus Galaxy Cluster.
In the same area of the sky are u. a. the galaxies IC 318 and IC 321 .
The Type Ia supernova SN 2002fk was observed here, the measurement of which contributed to the more precise determination of the distance.
The object was discovered on October 3, 1785 by the German-British astronomer Wilhelm Herschel .
