3C 223 is a Seyfert galaxy[1] located in the constellation of Leo Minor. It hosts a Type 2 quasar nucleus, found to be radio-loud with a rare, Compton-thick active galactic nucleus.[3][4]
3C 223 is also a radio galaxy.[5] With a projected size of ≥1 megaparsecs, it is classified a giant radio source according to researchers who presented Very Large Array images. Based on spectral study results, the source of 3C 223 is found to be younger.[6]
