'''HD 27274''', also known as '''Gliese 167''', is a solitary,<ref name = Rodriguez2015/> orange hued [[star]] located in the southern [[constellation]] [[Dorado]]. It has an [[apparent magnitude]] of 7.63,<ref name = Koen2010/> making it readily visible in binoculars, but not to the [[naked eye]]. Based on [[stellar parallax|parallax]] measurements from the [[Gaia spacecraft]], the star is known to be located 42.5 light-years (13.02 parsecs) away from the [[Solar System]]<ref name = GaiaDR3/> However, it is drifting closer with a heliocentric [[radial velocity]] of {{val|-23|ul=km/s}}. At its current distance, HD 27274 is dimmed down by 0.05 [[magnitude (astronomy)|magnitude]]s due to interstellar dust.<ref name = Gontcharov2017/>
'''Gliese 167''' is a K5-V [[spectral class|type]] [[star]] located 42.8 [[light years]] (13.1[[parsec|pc]]) from the [[sun]] and is found in the [[night]] [[sky]] at the co-ordinates [[right ascension|RA]] 04h 4m 9s and [[Declination|Dec.]] -53°26' in the [[constellation]] [[Dorado]] with an [[apparent magnitude]] of 7.62. [http://www.cthreepo.com/stars/view.php?HD=27274]


HD 27274 has a [[stellar classification]] of K4.5 Vk:,<ref name = Gray2006/> indicating that it is a [[K-type main-sequence star]] with interstellar [[Balmer lines|absorption features]]. However, there is uncertainty behind the classification. At present it has 73% the [[mass of the Sun]] and 70% of its [[Solar radius|radius]].<ref name = Stassun2019/> It has an [[effective temperature]] of {{val|4602|ul=K|fmt=commas}},<ref name = Casagrande2011/> but its small size yields a [[luminosity]] only 19.6% that of the [[Sun]].<ref name = GaiaDR3/> HD 27274 is metal enriched, having an [[iron]] abundance 44.6% above solar levels.<ref name = Casagrande2011/> The star spins with a [[projected rotational velocity]] of {{val|1|ul=km/s}},<ref name = Nordstrom2004/> and is estimated to be 4.5 [[billion years]] old.<ref name = Jenkins2006/> This is similar to the Sun's current age (4.6 Gyr).
The star has an [[absolute magnitude]] of 7.03, a [[parallax]] of 075.6 ± 09.4 [[Minute of arc|mas]] and a [[radial velocity]] of -23.2&nbsp;km/[[second|s]].

HD 27274, also known as Gliese 167, is a solitary,[11] orange hued star located in the southern constellation Dorado. It has an apparent magnitude of 7.63,[2] making it readily visible in binoculars, but not to the naked eye. Based on parallax measurements from the Gaia spacecraft, the star is known to be located 42.5 light-years (13.02 parsecs) away from the Solar System[1] However, it is drifting closer with a heliocentric radial velocity of −23 km/s. At its current distance, HD 27274 is dimmed down by 0.05 magnitudes due to interstellar dust.[12]

HD 27274 has a stellar classification of K4.5 Vk:,[3] indicating that it is a K-type main-sequence star with interstellar absorption features. However, there is uncertainty behind the classification. At present it has 73% the mass of the Sun and 70% of its radius.[6] It has an effective temperature of 4,602 K,[7] but its small size yields a luminosity only 19.6% that of the Sun.[1] HD 27274 is metal enriched, having an iron abundance 44.6% above solar levels.[7] The star spins with a projected rotational velocity of 1 km/s,[8] and is estimated to be 4.5 billion years old.[9] This is similar to the Sun's current age (4.6 Gyr).
