PKS 2000-330
PKS 2000-330 is a quasar located in the constellation Sagittarius. When identified in 1982, it was the most distant and most luminous object known.The "distance" of a far away galaxy depends on what distance measurement you use. With a redshift of 3.77, light from this active galaxy is estimated to have taken around 11.7 billion years to reach us. But since this galaxy is receding from Earth at an estimated rate of 274,681 km/s, the present distance to this galaxy is estimated to be around 22.7 billion light-years.
