Distance measurements

The "distance" of a far away galaxy depends on what distance measurement you use. With a redshift of 5.47, light from this active galaxy is estimated to have taken around 12.3 billion light-years to reach us. But since this galaxy is receding from Earth at an estimated rate of 285,803 km/s, the present distance to this galaxy is estimated to be around 26 billion light-years.
