10 Trianguli

10 Trianguli is a solitary[7] star located in the northern constellation Triangulum. It has an apparent magnitude of 5.28,[2] making it faintly visible to the naked eye under ideal conditions. The star is situated 363 light years[1] away and is thought to be moving further away with a heliocentric radial velocity of 0.457 km/s, although this value varies widely depending on the study.[8][9]

10 Trianguli has a stellar classification of A2 V.[3] It has 2.326 times the mass of the Sun and 3.651 times the radius of the Sun.[3] It shines at 85.4 times the luminosity of the Sun[3] from its photosphere at an effective temperature of 9183 K, giving it a blueish white glow.

Together with ι Trianguli and 12 Trianguli, it forms part of the obsolete Triangulum Minus.
