Orionids: The Orionid meteor shower, as mentioned above, showers the earth with meteors from the Halley's comet which orbits the sun every 75 to 76 years. The Orionids shower happens every October and can last for a week, treating patient observers to a show of 50-70 shooting stars per hour at its peak. Meteor showers are named after the constellations from where the shower appears to be coming from.
