NGC 1409 is a quiescent[4] lenticular galaxy in the equatorial constellation of Taurus. It was discovered by the German-born astronomer William Herschel on January 6, 1785.[6] NGC 1409 is located in close proximity to the smaller Seyfert galaxy NGC 1410, and the two are strongly interacting. Their respective nuclei have a separation of just 23 kly, and they share a diffuse stellar envelope with a radius extending out to 49 kly.[4]

The morphological classification of this galaxy most closely matches type SB0, which indicates a barred lenticular galaxy. There is a conspicuous pipeline of dust and gas being funneled to NGC 1409 from NGC 1410. This lane has a typical width of 330 ly, passing to the north in front of NGC 1409 and then behind, becoming denser toward the galactic core. It has an estimated mass of 3×108 M☉ and is transferring mass at the estimated rate of 1.1–1.4 M☉ yr–1. However, there is no indications of recent star formation in NGC 1409 from this incoming material.[4]
