'''NVSS 2146+82''' ('''WN B2147+81''') is a giant [[radio galaxy]], one of the largest known. At the time of its discovery in 2000, it was the second largest, second only to [[3C236]]. The optical counterpart to the radio object is a [[peculiar galaxy|peculiar]] giant [[elliptical galaxy]].<ref name=AJ-2000-05>Astronomical Journal, "Multiwavelength Observations of the Second-Largest Known Fanaroff-Riley Type II Radio Galaxy, NVSS 2146+82", Palma, Christopher; Bauer, Franz E.; Cotton, William D.; Bridle, Alan H.; Majewski, Steven R.; Sarazin, Craig L., Volume 119, Issue 5, pp. 2068-2084, ''May 2000'', {{arxiv|astro-ph/0002033}} , {{bibcode|2000AJ....119.2068P}} , {{doi|10.1086/301347}}</ref> The radio galaxy is {{convert|4.380|Mpc|Mly|abbr=on}} across.<ref name=AnA-2000-11>Astronomy and Astrophysics, "J1343+3758: the third largest FRII-type radio galaxy in the Universe", J.
