15 Trianguli is a suspected variable star located in the northern constellation Triangulum, with an apparent magnitude of 5.4 making it faintly visible to the naked eye under ideal conditions, although it is suspected of being an irregular variable with a range of 0.14 magnitudes. The star is situated about 480 light years away but is approaching with a heliocentric radial velocity of −8.646 km/s. 15 Trianguli has a stellar classification of M3 III. It has 1.7 times the mass of the Sun and 118 times the radius of the Sun. It has an effective temperature of 3,572 K and shines at 1,668 times the luminosity of the Sun from its photosphere, giving it an orange glow. It is an asymptotic giant branch star, which means it is fusing hydrogen and helium in separate shells around an inert carbon core. (en) 15 Trianguli är en misstänkt långsam irreguljär variabel av LB-typ (LB:) i stjärnbilden Triangeln . 15 Tri är en orange jätte som har visuell magnitud +5,39 och varierar i amplitud med 0,014 magnituder utan fastställd periodicitet.
