PKS 0438-436, also known as PKS J0440-4333, is a quasar located in constellation Caelum. With a high redshift of 2.86,[1] the object is located 11.2 billion light-years from Earth[2] and is classified as a blazar due to its flat-spectrum radio source,[3] (in terms of the flux density as (Fv ~ V-a) with α < 0.5 and its optical polarization.[4][5]
