'''HD 23005''', also known as '''HR 1124''', is a solitary,<ref name = Eggleton2008/> yellowish-white hued [[star]] located in the northern [[circumpolar constellation]] [[Camelopardalis]], the giraffe. It has an [[apparent magnitude]] of 5.78, making it faintly visible to the [[naked eye]]. The object is located relatively close at a distance of 173 [[light years]] based on [[Gaia DR3]] [[parallax]] measurements but is receding with a heliocentric [[radial velocity]] of {{val|4.9|ul=km/s}}.<ref name = Gontcharov2006/> At its current distance, HD 23005's brightness is diminished by 0.15 [[magnitude (astronomy)|magnitude]]s due to [[extinction (astronomy)|extinction]] from interstellar dust.<ref name = Gontcharov2017/> It has an [[absolute magnitude]] of +2.07.<ref name = Anderson2012/>
The star has been given several [[stellar classification]]s over the years. It has been given a [[luminosity class]] of a [[subgiant]] (IV),<ref name = Appenzeller1967/> a blend of a subgiant and [[main sequence star]] (IV/V),<ref name = Adams1935/> and a class intermediate between a [[bright giant]] and a regular [[giant star]] (II-III).<ref name = Cowley1976/> Most sources generally agree that it is an [[early-type star|early]] [[F-type star]].
HD 23005's newest spectral class is F1 IVnn, which indicates that it is an [[stellar evolution|evolved]] F-type subgiant with very broad [[absorption line|absorption]] features due to rapid rotation. It has 1.69 times the [[mass of the Sun]]<ref name = AP1999/> and an enlarged [[radius]] of {{solar radius|2.26|link=y}}.<ref name = Kervella2004/> It radiates 10.9 times the [[luminosity of the Sun]]<ref name = GaiaDR3/> from its [[photosphere]] at an [[effective temperature]] of {{val|6976|ul=K|fmt=commas}}.<ref name = Casagrande2011/> HD 23005 has an [[iron]] abundance 141% that of the [[Sun]]'s<ref name = Netopil2017/> and is estimated to be 1.1 [[billion years]] old.<ref name = Nordstrom2004/> Contrary to its suffix, the star spins modestly with a [[projected rotational velocity]] of {{val|66|ul=km/s}}. <ref name = "De Medeiros2014"/> A 2016 [[variable star]] survey identified HD 23005 as a candidate [[Gamma Doradus variable|γ Doradus variable]].<ref name = Karhman2016/>
