NGC 708 is an elliptical galaxy located 240 million light-years away[2] in the constellation Andromeda and was discovered by astronomer William Herschel on September 21, 1786.[3] It is classified as a cD galaxy[4][5] and is the brightest member of Abell 262.[6][7] NGC 708 is a weak[8] FR I radio galaxy[9][10][11][12][13] and is also classified as a type 2 Seyfert galaxy.[8][14][2]

NGC 708 is surrounded by 4,700 globular clusters.[15]
