JKCS 041 is a cluster of galaxies with the distinction, as of 2009, of being the farthest galaxy cluster observed from Earth. [1] It is estimated to be 10.2 billion light-years away, [2] seen at redshift 1.9. [3] The cluster is located in the constellation Cetus at a photometrically determined redshift of z=1.9 at right ascension 2h 26m 44s declination −04° 41′ 37″ ( J2000.0). [4] There are at least 19 members in the cluster. [2]
