It was discovered on April 6, 1785, by William Herschel and observed on February 19, 1827, by John Herschel.^[6] It is estimated to be 180 to 185 million light-years away, and its redshift-independent distance estimates to about 185 to 240 million light-years. It is around 75,000 light-years in diameter.^[7]^[6]

NGC 3902 is one galaxy within the NGC 3902 group (or LGG 254), a group of galaxies in Leo; the other galaxies of which are NGC 3920, NGC 3944, UGC 6806 and UGC 6807.
