Is it true that Orions stars are flying farther apart?
Actually these 3 prominent stars in the central region of the constellation Orion namely Alnitak, Alnilam and Mintaka are not actually too close with each other as we look in it from earth by our naked eyes. The linear alignment of the Belt is a line-of-sight effect that conceals somewhat the true relations of the stars making it up. In fact, the stars at either end of the Belt, Alnitak and Mintaka, are the closest together in space: Alnitak is a little over 800 light years from Earth, and Mintaka a hundred light years farther away. The central star, Alnilam, is much more distant than either of these, lying on the edge of the Orion Molecular Cloud more than 1,300 light years from the Solar System. Alnilam is the most massive and luminous of the three stars, so that despite its greater distance it still shines more brightly than its two companions. If the three stars were the same distance away, Alnilam would easily outshine the other Belt-stars. It is about 10,000 times more luminous t
