3C 212 is a quasar [1] located in the constellation Cancer. At redshift 1.048, it is one of the luminous and distant AGNs (Active Galactic Nuclei) observed. [3]

3C 212 is classified as radio-loud and is considered to be a prototype "red quasar", [4] [5] [6] with a faint optical counterpart. In additional, it is said to contain an X-ray absorber. [3]

A quasar is an extremely luminous active galactic nucleus (AGN). It is sometimes known as a quasi-stellar object, abbreviated QSO. The emission from an AGN is powered by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous accretion disc. Gas in the disc falling towards the black hole heats up and releases energy in the form of electromagnetic radiation. The radiant energy of quasars is enormous; the most powerful quasars have luminosities thousands of times greater than that of a galaxy such as the Milky Way. Quasars are usually categorized as a subclass of the more general category of AGN. The redshifts of quasars are of cosmological origin.
