Its story

15 Draconis drifts along the coils of the Dragon, that circumpolar serpent winding around the north celestial pole. A white A-class star —hotter than the Sun and clad in an almost pure hydrogen atmosphere— it reaches magnitude 4.94 from 487 light-years away. The light arriving tonight set out before any modern treatise had been written on the nature of our own Sun.
