NGC 1504 is an elliptical galaxy of Hubble type E / S0 in the constellation Eridanus at the southern sky . It is estimated to be 432 million light years from the Milky Way and about 90,000 light years in diameter. Due to the same distance and a similar radial velocity , it can be assumed that NGC 1504 and NGC 1505 are a gravitationally bound pair .

The object was discovered by Ormond Stone on December 31, 1885 .
