3C 223 is a Seyfert galaxy{{cite web |url=http://simbad.u-strasbg.fr/simbad/sim-id?Ident=3C+223 |title=Query : 3C 223 |website=Simbad |publisher=Centre de Données astronomiques de Strasbourg |access-date=2 June 2015}} 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.{{Cite journal |last1=LaMassa |first1=Stephanie M. |last2=Yaqoob |first2=Tahir |last3=Tzanavaris |first3=Panayiotis |last4=Gandhi |first4=Poshak |last5=Heckman |first5=Timothy |last6=Lansbury |first6=George |last7=Siemiginowska |first7=Aneta |date=2023-02-01 |title=The Complex X-ray Obscuration Environment in the Radio Loud Type 2 Quasar 3C 223 |journal=The Astrophysical Journal |volume=944 |issue=2 |pages=152 |doi=10.3847/1538-4357/acb3bb |doi-access=free |arxiv=2301.07193 |bibcode=2023ApJ...944..152L |issn=0004-637X}}{{Cite journal |last1=LaMassa |first1=Stephanie |last2=Yaqoob |first2=Tahir |last3=Tzanavaris |first3=Panayiotis |last4=Gandhi |first4=Poshak |last5=Heckman |first5=Timothy |last6=Lansbury |first6=George |last7=Siemiginowska |first7=Aneta |date=2023-01-01 |title=Exploring the Complex X-ray Spectrum of Radio Loud Type 2 AGN 3C 223 |journal=American Astronomical Society Meeting Abstracts |url=https://ui.adsabs.harvard.edu/abs/2023AAS...24141806L |volume=241 |pages=418.06|bibcode=2023AAS...24141806L }}

3C 223 is also a radio galaxy.{{Cite journal |last=Hogbom |first=J.

Based on spectral study results, the source of 3C 223 is found to be younger.{{Cite journal |last1=Orrù |first1=E. |last2=Murgia |first2=M. |last3=Feretti |first3=L. |last4=Govoni |first4=F. |last5=Giovannini |first5=G. |last6=Lane |first6=W. |last7=Kassim |first7=N. |last8=Paladino |first8=R. |date=2010-06-01 |title=Low-frequency study of two giant radio galaxies: 3C 35 and 3C 223 |url=https://www.aanda.org/articles/aa/abs/2010/07/aa13837-09/aa13837-09.html |journal=Astronomy & Astrophysics |language=en |volume=515 |pages=A50 |doi=10.1051/0004-6361/200913837 |arxiv=1003.0623 |bibcode=2010A&A...515A..50O |issn=0004-6361}}
