NGC 5865 , also listed twice in the catalog as NGC 5868 , is a 14.1 mag bright lens-shaped galaxy of the Hubble type E-S0 in the constellation Virgo and about 524 million light-years from Earth.
It forms a gravitationally bound double galaxy with NGC 5869 and was discovered on April 11, 1787 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as "pB, S, iE, lbM" (listed as NGC 5865 ) . However, Herschel's position information is incorrect, so that Heinrich Louis d'Arrest's observation on April 27, 1862 under NGC 5868 led to the second entry in the catalog.
