3C 452 is an elliptical galaxy [3] about 1.2 billion light years away located in the constellation Lacerta. 3C 452 is a Seyfert galaxy [1] [2] and a Fanaroff–Riley class 2 radio galaxy, with the radiolobes extending for about 5 arcminutes, which at the distance of 3C 452 corresponds to about 450 kiloparsecs. [4] Fainter radio lobes extend farther away, at megaparsec scales, probably created during a former period of elevated nuclear activity. [5] Diffuse X-ray emission has been detected in the radio lobes. [3]
