METEORS FROM HALLEY'S COMET: Earth is approaching a stream of debris from Halley's Comet, source of the annual Orionid meteor shower. Forecasters expect the shower to peak on Sunday, Oct. 22nd, with 15 to 20 meteors per hour. The best time to look is during the dark hours before sunrise when Orion the Hunter is high in the sky. The uptick in comets, asteroids, meteorites and fireballs is from the twin tails of the Nemesis-Nibiru system intersecting within our Solar System. See, All About Nibiru☆
