Its story

25 Sextantis belongs to the modest constellation of the Sextant, created by Hevelius in honour of the measuring instrument he lost in the fire that consumed his observatory in 1679. It is a blue B-type variable star, fiercely hot, whose brightness slowly oscillates and whose light crosses some three hundred and forty years before reaching Earth. A silent memorial, written in the sky, to the human effort of charting the stars.
