'''AU Microscopii''' (AU Mic) is a young [[red dwarf]] [[star]] located {{Convert|31.7|ly|pc|abbr=off|lk=on}} away &ndash; about 8 times as far as the closest star after the [[Sun]].<ref name="KALASETAL04"/> The [[apparent visual magnitude]] of AU Microscopii is 8.73,<ref name=aaa460_3_695/> which is too dim to be seen with the naked eye. It was given this [[Variable star designation|designation]] because it is in the southern constellation [[Microscopium]] and is a [[variable star]]. Like [[Beta Pictoris|β Pictoris]], AU Microscopii has a circumstellar disk of dust known as a [[debris disk]] and at least three [[exoplanet]]s, with the presence of an additional planet being likely.<ref name=Wittrock2023/><ref name="Donati2023"/>
