Orionids

Orionids

Annual rain of shooting stars, called this way because they seem to radiate from the homonymous constellation.

They become visible between October 11 and 30 of each year, with a maximum frequency on the 19th of the same month.

They are caused by detritus left along their own orbit by Halley's comet. This results in two annual showers of shooting stars, corresponding to two interceptions of its orbit with the Earth; the other rain is that of the Aquarids, which can be observed between April 29 and May 31 with a maximum frequency on May 5.
