The Orionid meteor shower, usually shortened to the Orionids, is the most prolific meteor shower associated with Halley's Comet. The Orionids are so-called because the point they appear to come from, called the radiant, lies in the constellation Orion. Orionids are an annual meteor shower which last approximately one week in late-October. In some years, meteors may occur at rates of 50-70 per hour. Meteor showers first designated 'shooting stars' were connected to comets in the 1800s. E.C. Herrick made an observation in 1839 and 1840 about the activity present in the October night skies. However A.S. Herschel produced the first documented record which produced accurate forecasts for the next meteor shower. The Orionid meteor shower is produced by the well-known Halley's Comet, which was named after the astronomer Edmund Halley and last passed through the inner solar system in 1986 on its 75-to-76-year orbit.
