'''HD 113337''' (LDS 2662 A) is the primary component of [[binary star]] system LDS 2662, about {{val|118|fmt=commas|u=[[light-years]]}} away from [[Earth]]. The primary [[main-sequence star]] belongs to the [[spectral class]] of F6. The star system is extremely young, and it is slightly enriched in [[heavy elements]], with an abundance of such elements at about 115% that of [[Sun|the Sun]].<ref name=Borgniet2019/>
