NGC 5266 is a 11.0 likes bright lenticular galaxy with an active galactic nucleus from Hubble type "E-S0" in the constellation Centaurus in the southern sky . It is estimated to be 127 million light years from the Milky Way and about 130,000 light years across . Together with the non-NGC object ESO 220-030 (also called NGC 5266A ), it forms a gravitationally bound galaxy pair .
The object was discovered on July 1, 1834 by John Herschel with an 18-inch reflector telescope, which she labeled “bright, round, very gradually little brighter in the middle; 45 arcseconds; has three 14th mag stars near ”. On a second observation he noted “bright, pretty large, slightly elongated, gradually a little brighter in the middle, resolvable, three very small stars nearby”.
