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 speed of light is 299,792 km/s), the present (co-moving) distance to this galaxy is estimated to be around 26 billion light-years (7961 Mpc).

Famous quotes containing the word distance:
“The particular source of frustration of women observing their own self-study and measuring their worth as women by the distance they kept from men necessitated that a distance be kept, and so what vindicated them also poured fuel on the furnace of their rage. One delight presumed another dissatisfaction, but their hatefulness confessed to their own lack of power to please. They hated men because they needed husbands, and they loathed the men they chased away for going.”
—Alexander Theroux (b. 1940)
