NGC 5603 (also NGC 5603A ) is a 13.0 may bright Lenticular galaxy with active galaxies core from the Hubble type S0 in the constellation Bootes the northern sky . It is an estimated 257 million light years from the Milky Way and about 80,000 light years in diameter. Together with the non-NGC object PGC 51372 (also NGC 5603B ) it forms the gravitationally bound galaxy pair Holm 641 .
In the same area of the sky are u. a. the galaxies NGC 5582 , NGC 5598 , NGC 5601 .
The object was discovered on April 29, 1788 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as "cF, pS".
