Its story

2 Hydrae is a young white A-type star, only 163 light-years away, in the long body of Hydra. It vibrates with faint variations in brightness, that delicate, rapid pulsation typical of young A-class stars still finding their inner balance. Its distance is relatively small in cosmic terms: the light crossing the atmosphere tonight left its surface in the middle of the second half of the nineteenth century, almost on the edge of modern photography.
