The earth enters a stream of debris from Halley’s comet, the source of the annual meteor shower of the Orionids. Just last night, NASA’s network of meteorological cameras detected 23 fireballs over the US – the result of dust falling into the comet at a speed of over 65 km / s.
Predictors expect that the meteor shower will reach a peak on October 21-22 with 25 meteors per hour. The best time to watch is in the dark hours before dawn, when the constellation of Orion will be high in the sky.
