NGC 5365 is an 11.4 mag bright, lens-shaped galaxy of the Hubble-type SB0 in the constellation Centaur that is approximately 103 million light years from the Milky Way . Together with the roughly equally distant non-NGC objects PGC 49586 (also called NGC 5365A ) and PGC 49750 (also called NGC 5365B ), it forms a gravitationally bound triple galaxy.
NGC 5365 was discovered on March 15, 1836 by John Herschel with an 18-inch reflector telescope, which, upon two observations, “pretty bright, very small, round, gradually brighter in the middle; 15 arcseconds "and" pretty faint, small, round, pretty gradually much brighter in the middle; in a group of small stars ”.
