'''Mu Arae''' is a single [[star]] with a [[planetary system]] in the [[constellation]] of [[Ara (constellation)|Ara]]. Its name is a [[Bayer designation]] that is [[Romanization of Greek|Latinized]] from '''μ Arae''', and abbreviated '''Mu Ara''' or '''μ Ara'''. This star is officially named '''Cervantes''', pronounced  {{IPAc-en|s|ɜːr|'|v|æ|n|t|iː|z}} or {{respell|sur|VAN|teez}},<ref name="IAU-CSN"/> and is often designated '''HD&nbsp;160691'''. With an [[apparent visual magnitude]] of 5.15,<ref name="Benedict2022"/> it is faintly visible to the [[naked eye]]. Based on [[stellar parallax|parallax]] measurements it is located approximately {{convert|51|ly|pc|abbr=out|lk=on}} away from the [[Sun]].<ref name=GaiaDR3/> It is drifting closer with a [[radial velocity]] of −10&nbsp;km/s.<ref name=GaiaDR3/>

Cervantes is similar to the Sun, but is older, 10% more massive, and slightly [[stellar evolution|evolved]]. It has four known [[Exoplanet|extrasolar planets]] designated [[Mu Arae b]], [[Mu Arae c|c]], [[Mu Arae d|d]] and [[Mu Arae e|e]]; later named Quijote, Dulcinea, Rocinante and Sancho, respectively. Three of them have masses comparable with that of [[Jupiter]]. Mu Arae c, the innermost, was the first [[hot Neptune]] or [[super-Earth]] discovered.
