NGC 4436 is a lenticular or dwarf elliptical galaxy located about 60 million light-years away[3][4] in the constellation of Virgo.[5] NGC 4436 was discovered by astronomer William Herschel on April 17, 1784.[6] The galaxy is a member of the Virgo Cluster.[7]
Interaction with NGC 4431
NGC 4436 is undergoing a tidal interaction with a nearby dwarf elliptical galaxy known as NGC 4431. The two galaxies are separated by around 58,680 light-years (18 kpc).[8]
