Catch the Orionid Meteor Shower: A Guide for Stargazers

EarthSun Oct 20 2024
Halley's comet, on its 76-year journey around the sun, left a trail of debris that creates an annual meteor shower called the Orionid meteor shower. This celestial event peaks on Sunday night and Monday, offering a great chance to see 10 to 20 meteors per hour. The best viewing time is after midnight when the Orion constellation is high in the sky, with the show visible everywhere except Antarctica. Even a few days after the peak, the display remains active. To spot these meteors, find a dark spot and let your eyes adjust for about 30 minutes. The moon, which appears as a supermoon known as the hunter's moon, will be less disruptive towards the end of October. Watching in the opposite direction from the moon helps in seeing fainter meteors. The Orionids are active until November 22. Twice a year, Earth crosses Halley's comet's debris trail. The first encounter in May produces the Eta Aquariids, and the second in October creates the Orionids. As particles enter Earth's atmosphere, they burn up, creating the meteors we see. Larger particles can produce fireballs, brighter than Venus. Unlike asteroids that sometimes reach the ground as meteorites, comets made of ice and gas usually disintegrate in the atmosphere. Sky-gazers enjoy the Orionids because they connect with nature and the universe's constant motion. Each night and year are unique, with everything moving slightly. This year, stargazers can also look out for Comet C/2023 A3 Tsuchinshan-ATLAS until early November. Two more full moons, the beaver moon (a supermoon) on November 15 and the cold moon on December 15, are also upcoming. The meteor shower season ends with the Southern Taurids, Northern Taurids, Leonids, Geminids, and Ursids.
