| dbo:abstract | 7 Trianguli is a solitary star located in the northern constellation Triangulum. It has an apparent magnitude of 5.25, making it faintly visible to the naked eye under ideal conditions. The star is situated at distance of 360 light years but is approaching with a heliocentric radial velocity of −1.3 km/s, which is poorly constrained. 7 Trianguli has a stellar classification of A0 V or B9.5 V, depending on the study. At present it has 2.77 times the mass of the Sun and 3.24 times the radius of the Sun. It shines at 89.1 times the luminosity of the Sun from its photosphere at an effective temperature of 10,685 K, giving it a blueish white glow. 7 Trianguli is a young star, with an age of 283 million years and spins rapidly with a projected rotational velocity of 130 km/s. It has been classified as having a peculiar spectrum, but it is considered doubtful that it is actually a chemically peculiar star. Together with δ Trianguli and γ Trianguli, it forms an optical (line-of-sight) triple.
