Orionid Meteor Shower 2010


The Orionid meteor shower peaks on Thursday morning, October 21st, 2010, at 10:00 am, MDT. Best viewing would be the nights of the 20th and 21st. The predicted peak rate for the Orionids is 20 meteors per hour. Unfortuantely, a full moon on the 22nd will wash out most meteors.

The Orionids are the result of Halley’s Comet, which last passed by Earth in 1986 and won’t return again until 2061. The name ‘Orionids’ comes from the constellation Orion, which contains the radiant of the shower.

The radiant is the source point for Orionid meteors. Even though meteors can be seen across the sky, if you trace backward the familiar streak of light for a number of meteors, you will find that they converge in the constellation of Orion.
