NGC 4767 is a 11.5 likes bright elliptical galaxy from the Hubble type E in the constellation Centaurus and about 126 million light-years from the Milky Way center. Together with the non-NGC objects PGC 43744 (often also called NGC 4767 A ) and PGC 43954 (also NGC 4767 B ), it forms an optical three-way constellation.
It was discovered on April 21, 1835 by John Herschel with an 18-inch reflector telescope, who marked it with “bright, small, slightly elongated, pretty suddenly much brighter in the middle; 25 arcseconds. Wind violent ”. On a second observation he noted “pretty faint, small, round, not 1st class”, and his last observation he commented “pretty bright, pretty large, slightly elongated, gradually much brighter in the middle; 40 arcseconds ".
