NGC 3640 is an elliptical galaxy located in the constellation Leo. It is located at a distance of circa 75 million light years from Earth, which, given its apparent dimensions, means that NGC 3640 is about 90,000 light years across. It was discovered by William Herschel on February 23, 1784.[3] It is a member of the NGC 3640 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.[4]
It lies 2 degrees south of Sigma Leonis and is a member of the Herschel 400 Catalogue. It is condensed and can be spotted with a small telescope from suburban skies.[5]
