3C 459 contains a triple radio structure, measuring a total extent of 29 kiloparsecs (kpc).{{Cite journal |last=Ulvestad |first=J.

The radio core in 3C 459 has a compact steep radio spectrum with east and west extensions.{{Cite journal |last1=Farrah |first1=D. |last2=Rowan-Robinson |first2=M. |last3=Oliver |first3=S. |last4=Serjeant |first4=S. |last5=Borne |first5=K. |last6=Lawrence |first6=A. |last7=Lucas |first7=R.A. |last8=Bushouse |first8=H. |last9=Colina |first9=L. |date=October 2001 |title=HST/WFPC2 imaging of the QDOT ultraluminous infrared galaxy sample |journal=Monthly Notices of the Royal Astronomical Society |volume=326 |issue=4 |pages=1333–1352 |doi=10.1111/j.1365-2966.2001.04721.x |doi-access=free |arxiv=astro-ph/0106275 |bibcode=2001MNRAS.326.1333F |issn=0035-8711}} As for the lobes on the other hand, the western lobe is equally 5.5 times further from the nucleus, while the eastern lobe is compact and more closer.{{Cite journal |last1=Morganti |first1=R. |last2=Oosterloo |first2=T. |last3=Tadhunter |first3=C.N. |last4=Aiudi |first4=R. |last5=Jones |first5=P. |last6=Villar-Martin |first6=M. |date=December 1999 |title=The radio structures of southern 2-Jy radio sources: New ATCA and VLA radio images |url=https://aas.aanda.org/articles/aas/pdf/1999/21/ds1732.pdf |journal=Astronomy & Astrophysics Supplement Series |volume=140 |issue=3 |pages=355–372|doi=10.1051/aas:1999427 |arxiv=astro-ph/9910150 |bibcode=1999A&AS..140..355M }} It is also indicated to be significantly depolarized by interstellar medium since only the western lobe shows strong polarization.

According to follow-up observation by Chandra X-ray Observatory in 2014, 3C 459 shows X-ray emission properties. Although most X-ray emission originates from the radio core, a significant amount of it is found at larger angular separations from the core, surrounding the galaxy's lobes and radio jets.{{Cite journal |last1=Maselli |first1=A. |last2=Kraft |first2=R.

There is also detections of diffused nuclear emissions and a filamentary ionized gas structure in 3C 459 creating a single-sided triangular-shaped region with an outward expansion of up to ~ 80 kpc. In its central emission line region, it is dominated by two compact knots of similar flux. Both of them are found to have an offset of ~ 400 km s-1 from velocity point of view suggesting a dual active galactic nuclei (AGN) system in 3C 459.{{Cite journal |last1=Balmaverde |first1=B. |last2=Capetti |first2=A. |last3=Marconi |first3=A. |last4=Venturi |first4=G. |last5=Chiaberge |first5=M. |last6=Baldi |first6=R.
