2019 527243 KAT-01, often shortened to 2019 KAT-01, or simply KAT-01 is a trans-Neptunian object discovered in 2019 by the Lod'oka Observatory in 2019. Estimated to be only 1,000 kilometers in diameter, KAT-01 is one of the most distant planetary objects observed, especially by a Garetolian observatory. There is some debate over who discovered KAT-01, since the Caltech Submillimeter Observatory also claimed to have discovered the object a few months prior. However, this claim is likely a hoax; the observed object may have been either Sedna or a rogue asteroid
