The object's name is derived from its location in the GOODS-North field of galaxies and its high cosmological redshift number (GN + z11).[12] It is observed as it existed 13.4 billion years ago, just 400 million years after the Big Bang;[4][13][14] as a result, its distance is sometimes inappropriately[15] reported as 13.4 billion light-years, its light-travel distance measurement.[16][17]
In early 2023, James Webb Space Telescope observed the galaxy and reported a definitive redshift of z = 10.6034 ± 0.0013.[2]
The galaxy has such a high redshift that its angular diameter distance is actually less than that of some galaxies with lower redshift. This means that the ratio of its angular size to its size in light-years is greater.[clarification needed]
