045

F200DB-045 is a candidate high-redshift galaxy, with an estimated redshift of approximately z = 20.4, corresponding to 168 million years after the Big Bang. If confirmed, it would be one of the earliest and most distant known galaxies observed.
F200DB-045 would have a light-travel distance (lookback time) of 13.7 billion years, and, due to the expansion of the universe, a present proper distance of 36.1 billion light-years.
Nonetheless, the redshift value of the galaxy presented by the procedure in one study may differ from the values presented in other studies using different procedures.
