'''HD 76151''' is a high [[proper motion]], [[G-type main-sequence star]] and [[solar analog]]<ref name="Senturk2024"/> in the [[constellation]] of [[Hydra (constellation)|Hydra]] 54.95 [[light-year]]s from Earth.<ref name=GaiaDR3/> It has an [[apparent visual magnitude]] of approximately 6.00, which means it is faintly visible to the naked eye under good viewing conditions.<ref name=sb0 /> An [[infrared excess]] has been detected around this star, most likely indicating the presence of a [[circumstellar disk]] at a radius of 7.9 [[Astronomical Unit|AU]]. The temperature of this dust is 99 K.<ref name="aa555_A11" />
HD 76151 has an age of roughly 5.5 billion years old, with estimates ranging from 3.4 to 9.6 billion years. The [[stellar atmosphere]] has an [[effective temperature]] of around {{convert|5790|K|C F|lk=on}}. The radius of HD 76151 is {{convert|1.125|solar radius|km}} based on [[Astronomical spectroscopy|spectroscopic]] observations, though [[Gaia DR3]] estimates a radius of {{convert|0.977|solar radius|km}}. It is slightly [[metallicity|metal-rich]] and is a member of the [[thin disk]] population.<ref name="Senturk2024"/>
