'''10 Trianguli''' is a solitary<ref name=Eggleton2008/> star located in the northern [[constellation]] [[Triangulum]]. It has an [[apparent magnitude]] of 5.28,<ref name = Fracassini2001/> making it faintly visible to the [[naked eye]] under ideal conditions. The star is situated 363 [[light years]]<ref name = EDR3/> away and is thought to be moving further away with a heliocentric [[radial velocity]] of {{val|0.457|ul=km/s}}, although this value varies widely depending on the study.<ref name=gontcharov2018/><ref name=gebran2016/>
'''10 Trianguli''' ('''HD 14252; HR 675; 1 H. Trianguli Minus'''), or simply '''10 Tri''' is a solitary [[star]]<ref name=Eggleton2008/> located in the northern [[constellation]] [[Triangulum]]. It is faintly visible to the [[naked eye]] as a white-hued point of light with an [[apparent magnitude]] of 5.29.<ref name = Tycho2000/> [[Gaia DR3]] [[parallax]] measurements imply a distance of 363 [[light-year]]s <ref name = EDR3/> and it is slowly receding with a heliocentric [[radial velocity]] of {{val|0.4|ul=km/s}}.<ref name = Gontcharov2006/> At its current distance, 10 Tri's brightness is diminished by an [[interstellar extinction]] of 0.11 [[magnitude (astronomy)|magnitude]]s<ref name = Gontcharov2017/> and it has an [[absolute magnitude]] of −0.02.<ref name = Anderson2012/>


10 Trianguli has a [[stellar classification]] of A2 V.<ref name = Stassun2019/> It has 2.326 times the [[mass of the Sun]] and 3.651 times the [[radius of the Sun]].<ref name = Stassun2019/> It shines at 85.4 times the [[luminosity of the Sun]]<ref name = Stassun2019/> from its [[photosphere]] at an [[effective temperature]] of 9183 [[Kelvin|K]], giving it a blueish white glow.
10 Trianguli has a [[stellar classification]] of A2 V,<ref name = Osawa1959/><ref name = Cowley1969/> indicating that it is an ordinary [[A-type main-sequence star]] that is generating energy via [[hydrogen fusion]] at its [[stellar core|core]]. It has 2.83 times the [[mass of the Sun]]<ref name = Zorec2012/> and a slightly enlarged [[radius]] 3.71 times that of the [[Sun]].<ref name = Kervella2004/> It radiates 108 times the [[luminosity of the Sun]]<ref name = Zorec2012/> from its [[photosphere]] at an [[effective temperature]] of {{val|9023|ul=K|fmt=commas}}.<ref name = Takeda2019/> 10 Trianguli is rather evolved for its class, having completed 92.5% of its [[main sequence]] lifetime<ref name = Zorec2012/> at the age of 372 [[million years]].<ref name = Gontcharov2012A/><ref name = Gontcharov2012B/> It is metal enriched with an [[iron]] abundance of [Fe/H] = +0.33 or % of the Sun's<ref name = Gerban2016/> and unlike most hot stars, it spins modestly with a [[projected rotational velocity]] of {{val|22|ul=km/s}}.<ref name = Royer2002/>


Together with [[ι Trianguli]] and [[12 Trianguli]], it forms part of the obsolete [[Triangulum Minus]].
10 Trianguli has a 13th magnitude companion located 58.3" away along a [[position angle]] of 205°.<ref name = Mason2001/> It is an unrelated background star that is much more distant than 10 Trianguli.<ref name = EDR3B/> Together with [[ι Trianguli]] and [[12 Trianguli]], it forms part of the obsolete [[Triangulum Minus]].

10 Trianguli (HD 14252; HR 675; 1 H. Trianguli Minus), or simply 10 Tri is a solitary star[17] located in the northern constellation Triangulum. It is faintly visible to the naked eye as a white-hued point of light with an apparent magnitude of 5.29.[2] Gaia DR3 parallax measurements imply a distance of 363 light-years [1] and it is slowly receding with a heliocentric radial velocity of 0.4 km/s.[7] At its current distance, 10 Tri's brightness is diminished by an interstellar extinction of 0.11 magnitudes[18] and it has an absolute magnitude of −0.02.[8]

10 Trianguli has a stellar classification of A2 V,[4][5] indicating that it is an ordinary A-type main-sequence star that is generating energy via hydrogen fusion at its core. It has 2.83 times the mass of the Sun[3] and a slightly enlarged radius 3.71 times that of the Sun.[9] It radiates 108 times the luminosity of the Sun[3] from its photosphere at an effective temperature of 9,023 K.[11] 10 Trianguli is rather evolved for its class, having completed 92.5% of its main sequence lifetime[3] at the age of 372 million years.[14][15] It is metal enriched with an iron abundance of [Fe/H] = +0.33 or % of the Sun's[12] and unlike most hot stars, it spins modestly with a projected rotational velocity of 22 km/s.[13]

10 Trianguli has a 13th magnitude companion located 58.3" away along a position angle of 205°.[19] It is an unrelated background star that is much more distant than 10 Trianguli.[20] Together with ι Trianguli and 12 Trianguli, it forms part of the obsolete Triangulum Minus.
