NGC 5011 is a 11.3 likes bright elliptical galaxy from the Hubble type E1 in the constellation Centaurus , which is about 134 million light-years from the Milky Way center. Together with the non-NGC objects PGC 45847 (also called NGC 5011 A ), PGC 45918 (NGC 5011 B) and PGC 45917 (NGC 5011 C), it forms an optical galaxy group and was created on June 3, 1834 by John Herschel with a 18-inch reflector telescope discovered, which you can see with "pretty bright, pretty small, round, gradually brighter in the middle; 15 arcseconds; in a curve of 3 or 4 stars ”. On a second observation he noted “pretty bright, round, small, pretty gradually brighter in the middle; 12 arcseconds. In the middle of an arc of four stars "; his third note was “pretty faint, small, round. The middle object in an arc of stars ".
