WAKE COUNTY, N.C. — The Orionid meteor shower peaks this weekend, building to its expected peak the morning of Sunday, Oct. 21.

Some meteors may be visible Friday night into Saturday morning as well. From a dark site, about 10-20 meteors per hour are expected.

What sets the Orinids apart is their speed and trains.

While the meteors themselves are faint than in other showers, they are fast.

Traveling through the atmosphere at over 40 miles per second. They also leave persistent trains, trails of ionized gas that last for seconds after the meteor.

Like other meteor showers, the Orionids are created by sand-sized bits of rock and dust left behind as by a comet passes through our part of the solar system.

Orionids are created by comet 1P/Halley, better known as Halley's Comet, as it passed Earth’s orbit after diving past the sun. Halley’s Comet also leaves a similar trail on its way in, powering the Eta Aquariids in early May.

The best time to see the Orionids will be Sunday morning between 4 a.m. and 6:30 a.m., after the waxing gibbous moon sets but before the rising Sun brightens the eastern sky

Meteors can appear anywhere in the sky but the Orionids appear to be originate from a point above the right shoulder of the constellation Orion the hunter.
