SUMMARY: You might want to set your alarm clock a little earlier on Thursday morning, so you can enjoy the Orionid meteor shower. If you look towards the constellation of Orion, with its easy to find belt, and be patient, you should see at least a few meteors streak past in the sky. This annual event happens because the Earth is passing through the dust trail of Halley's Comet, which returns to the Sun every 76 years. Orionids move fast, striking the atmosphere at 66 km/s (148,000 mph), which means they can be more spectacular that other, slower moving meteor showers. In dark conditions, you can expect to see 15-30 meteors an hour; less in the city.
