October, the autumn wind brings a refreshing autumn wind, is a good time to watch the star. According to astronomical organizations, this year's Orion meteor shower will arrive around 2 a.m. on October 22, with the maximum period of ZHR ~ 20 (ZHR is the number of meteors that can be seen per hour when the radiation point is directly above the head). This means that under ideal observation conditions, we can see up to 20 meteors per hour!
Around 8:30 tonight, Dahe Daily Yu Video "Shining Stars" and Jinan Seven Star Observatory will present you with a 24-hour live broadcast of Orion meteor shower. Stay tuned!
Orion meteor shower brings a romantic show tonight, watch live broadcast and meteor shower "Two-way"
Tonight, the night sky "stage" will stage a meteor shower show: Orion meteor shower arrives as scheduled.
Orion meteor shower is one of the seven meteor showers in the world. It has the characteristics of many bright meteors, relatively stable flow, long trajectory, and long peak flow duration. Its active period is generally between October 2 and November 7 of each year. It can be said to be the most anticipated astronomical wonder in October.
What are the overall observation conditions of this Orion meteor shower?
Niu Guihua, the founder of Jinan Seven Star Observatory, told reporters that around 10:00 tonight (October 21), the radiation point of the meteor shower will rise from the east. Because it is almost unaffected by moonlight, observers in most parts of the world can enjoy this meteor feast. "Since the direction of Halley's comet, the parent body of the Orion meteor shower, is opposite to the direction of the earth, there are often more meteors you can see in the second half of the night than in the first half of the night," said Niu Guihua.
How do our Henan star chasers observe this meteor shower?
Take Zhengzhou as an example. According to "Astronomy Pass", Zhengzhou has better star-watching conditions tonight, with high-altitude cloud volume and total cloud volume almost 0%. The moonless night (after sunset, the time period when there is no moon in the sky, which is the recommended time for stargazing) is 19:09-02:59, and the time when the moon jumps out of the horizon is 2:59 am on October 22. Niu Guihua suggested that in order to reduce the impact of moonlight on stargazing, astronomical enthusiasts can observe in places with less light damage and wide vision from midnight to about 30 minutes before "moonrise".
Why is the meteor shower produced by Halley's Comet called "Orion meteor shower"?
Comets are one of the sources of meteors. When comets move around orbit, they will leave a large number of dust particles. When the earth meets these dust particles along orbit, the particles fall into the atmosphere and burn to form ashes, which will form a meteor shower.
Orion meteor shower is a medium-flow meteor shower. When it comes to its origin, we have to mention its parent body - the famous Halley Comet. The Earth passes through Halley's Comet twice a year, one of which is in October. Orion is one of the equatorial constellations. Every October, the radiation point of the meteor shower is in Orion, so this "romantic appointment" is named Orion meteor shower.
Tomorrow is the weekend, so why not stay up all night together! Star fans who have the conditions can go outdoors for observation. Star fans who want to watch the meteor shower without leaving home can also "go in both directions" with this meteor shower online through the 24-hour live broadcast brought to you by Dahe Daily Yu Video "Shining Stars" and the Seven-Star Observatory.
