NGC 777

NGC 777 is an elliptical galaxy in the constellation of Triangulum. It was discovered by William Herschel on September 12, 1784. It has a weak active nucleus of type Seyfert 2 or LINER 2,^[4] implying that the central region is obscured. It may be an outlying member of galaxy cluster Abell 262.^[5]
