'''Microscopium''' ("the [[Microscope]]") is a minor [[constellation]] in the [[southern celestial hemisphere]], one of twelve created in the 18th century by French [[astronomer]] [[Nicolas-Louis de Lacaille]] and one of several depicting scientific instruments. The name is a [[Latin]]ised form of the [[Ancient Greek|Greek]] word for [[microscope]]. Its [[star]]s are faint and hardly visible from most of the non-tropical [[Northern Hemisphere]].

The constellation's brightest star is [[Gamma Microscopii]] of [[apparent magnitude]] 4.68, a yellow giant 2.5 times the Sun's mass located 223 ± 8&nbsp;light-years distant. It passed within 1.14 and 3.45 light-years of the Sun some 3.9 million years ago, possibly disturbing the outer Solar System. Three star systems—[[WASP-7]], [[AU Microscopii]] and [[HD&nbsp;205739]]—have been determined to have [[exoplanet|planets]], while other star —the Sun-like star [[HD 202628]]— has a [[debris disk]]. AU Microscopii and the binary red dwarf system [[AT Microscopii]] are probably a wide triple system and members of the [[Beta Pictoris moving group]]. Nicknamed "Speedy Mic", [[BO Microscopii]] is a star with an extremely fast rotation period of 9&nbsp;hours, 7&nbsp;minutes.
