Star in the constellation Triangulum
10 Trianguli (HD 14252; HR 675; 1 H. Trianguli Minus ), or simply10 Tri is a solitarystar [ 17] constellation Triangulum . It is faintly visible to thenaked eye as a white-hued point of light with anapparent magnitude of 5.29.[ 2] Gaia DR3 parallax measurements imply a distance of 363light-years [ 1] radial velocity ofkm/s [ 7] interstellar extinction of 0.11magnitudes [ 18] absolute magnitude of −0.02.[ 8]
10 Trianguli has astellar classification of A2 V,[ 4] [ 5] A-type main-sequence star that is generating energy viahydrogen fusion at itscore . It has 2.83 times themass of the Sun [ 3] radius 3.71 times that of theSun .[ 9] luminosity of the Sun [ 3] photosphere at aneffective temperature ofK [ 11] main sequence lifetime[ 3] million years .[ 14] [ 15] iron abundance of [Fe/H] = +0.33 or % of the Sun's[ 12] projected rotational velocity ofkm/s [ 13]
10 Trianguli has a 13th magnitude companion located 58.3" away along aposition angle of 205°.[ 19] [ 20] ι Trianguli and12 Trianguli , it forms part of the obsoleteTriangulum Minus .
It was once designateda Trianguli byJohn Flamsteed and was included in his Atlas Coelestis, but the designation is now dropped.[ 21]
