NGC 4056 is an elliptical galaxy[2] located about 340 million light-years away[3] in the constellation Coma Berenices. The galaxy was discovered by astronomer Albert Marth on March 18, 1865[2] and is a member of the NGC 4065 Group.[4]
Although NGC 4056 is commonly equated with PGC 38140, there is still uncertainty in its identification.[2][3][5]
