NGC 4773 is a double optical galaxy in the constellation Virgo . The objects are listed in the catalog under NGC 4759A and NGC 4759B and are bright, lenticular galaxies of the Hubble type S0. NGC 4759A is approximately 154 million light years away from the Milky Way, while NGC 4759B is 185 million light years away.
When it was discovered on March 25, 1786, Wilhelm Herschel mistook it for an object, described it with "F, S" and thus gained an entry in the catalog.
Only John Herschel was able to resolve them into the two individual objects during his observation on May 5, 1836, which are now listed under NGC 4776 and NGC 4778 .
