What is 10 Triangulum
10 Trianguli is a white A-type star 377 light-years away, set in the small Triangulum, one of the most ancient and compact constellations of the northern sky. Its surface near nine thousand degrees gives it the bright white tone typical of A stars. The constellation —neighbour to Andromeda— is famous for hosting M33, a spiral galaxy of the Local Group, though that diffuse glow lies far behind this star.
