NGC 1404 is an elliptical galaxy in the Southern constellation Eridanus. It was discovered on November 28, 1837, by the astronomer John Herschel.{{cite web|url=http://cseligman.com/text/atlas/ngc14.htm#1404|title=New General Catalogue objects: NGC 1400 - 1449|author=Seligman, Courtney|website=cseligman.com|accessdate=2021-02-21}} Based on the tip of the red-giant branch distance indicator, it lies at a distance of approximately 60 million light-years from the Milky Way. It is one of the brightest members of the Fornax Cluster.{{cite web |title=Falling in Fornax |url=https://www.eso.org/public/images/potw1943a/ |website=www.eso.org |access-date=28 October 2019 |language=en}}{{Cite journal

Characteristics
As usual with most elliptical galaxies, NGC 1404 is rich in globular clusters, with a population of them that has been estimated to be around 725;{{Cite journal
