How does the Orionid meteor shower originate?

The maximum peak of the Orionid meteor shower arrives between the nights of October 20 and 22, although its observation is complicated this year with a less dark sky due to the full moon.

Every year from mid to late October, the Earth passes through a stream of dusty debris from Halley’s Comet and the sky, before dawn, can be illuminated with a beautiful array of shooting stars.

“We expect to see around 20-25 meteors per hour when the shower peaks during the early morning of”, says in a statement Bill Cooke, head of NASA’s Office of the Meteoroid Environment.

Since these meteors come out of the constellation Orion, astronomers call them “Orionids.” It is not the strongest, but it is one of the most beautiful rains of the year “, highlights Cooke.

The cause is your environment:. Constellations such as Taurus, Gemini, and Orion provide a brilliant backdrop for the show. The brightest star of all, Sirius (Sirius), is located just below Orion’s left foot, which is a good place to point the camera while waiting for meteors.

Even though the constellation Orionids emerges from a small area located near Orion’s shoulder, meteors will flood the entire sky. Meteoroids from Halley’s Comet pass through Earth’s atmosphere, traveling at around 238,000 kilometers per hour. , which arrive in November, are faster.

Speed ​​is important because fast meteors have a tendency to explode. Occasionally, Orionid fireballs leave streams of incandescent debris that last for several minutes. Such wind-twisted filaments in the upper atmosphere take on twisted shapes that can even be prettier than the meteors themselves.
