Its story

17 Pegasi is a blue-white A2Vnn main-sequence star roughly 401 light-years away in the great square of the Winged Horse. Its effective temperature hovers near 9,100 K, and it shines more than eighty times brighter than the Sun. The double «n» in its spectral type marks rotation so rapid that its spectral lines visibly broaden: it spins like a young top that has yet to know the friction of time.
