'''HD 97413''' is a [[binary star]] located in the southern [[constellation]] [[Centaurus]]. The system has a [[combined magnitude]] of 6.27,<ref name = Tycho2000/> placing it near the limit for [[naked eye]] visibility. Based on [[parallax]] measurements from the [[Gaia spacecraft]], the system is located 320 [[light year]]s away from the [[Solar System]].<ref name = GaiaDR3/>

The objects binarity was detected in a [[Hipparcos]] survey. The two components can't be distinguished because both stars have an [[angular separation]] of {{val|0.01|ul=arcsecond}}.<ref name = Mason2001/> Nevertheless, [[speckle interferometry]] revealed the components to have a 2.6 [[magnitude (astronomy)|magnitude]] difference.<ref name = Tokovinin2019/> They are located along a [[position angle]] of 250°.<ref name = Mason2001/>

The visible component – HD 97413 A – has a [[stellar classification]] of A1 V, indicating that it is an ordinary [[A-type main-sequence star]]. It has 1.94 times the [[mass of the Sun]]<ref name = AP1999/> and a radius of {{solar radius|2.18|link=y}}.<ref name = TIC/> It radiates 19.6 times the [[luminosity of the Sun]]<ref name = McDonald2012/> from its [[photosphere]] at an [[effective temperature]] of {{val|7800|ul=K|fmt=commas}},<ref name = McDonald2012/> giving it a white hue. However, this is not typical for an A1 star. Parameters determined by Gaia's [[extinction (astronomy)|extinction]] reveal HD 97413 A to have an [[iron]] abundance half of the [[Sun]]'s,<ref name = Anders2019/> making it metal deficient.
