'''Comet ATLAS''', formally designated as '''C/2019 E3''', is an [[Oort cloud]] [[comet]] with a very distant perihelion of {{convert|10.30|AU|e9km|abbr=unit}}, the third known comet with a perihelion distance beyond 10 AU after [[167P/CINEOS]] and [[C/2003 A2 (Gleason)]].{{r|jpl|Fernandez_2019}}

Precovery observations of this comet all the way to 2016 (and later 2012){{r|jpl}} have revealed that the comet had produced some cometary activity more than {{convert|20|AU|e9km|abbr=unit}} from the [[Sun]], making it the fourth known distant comet to produce such activity at large distances after [[C/2010 U3 (Boattini)]], [[C/2014 UN271 (Bernardinelli–Bernstein)]], and [[C/2017 K2 (PanSTARRS)]].{{r|Hui_2024}}
