I believe that the most talked about recently is the double 11 shopping, but maybe your double 11 package hasn't arrived yet, and this year's "meteor shower king" has arrived first.

According to the astronomical forecast,With the title of "king of meteor shower", the Leonid meteor shower will usher in a huge event on November 18

The Leo meteor shower is a meteor shower connected to Comet Temple Tuttle, which has a period of about 33 years.It occurs from November 14 to 21 every year, and the maximum usually occurs around November 17 and 18

Generally speaking, the number of meteors is about 10 to 15 per hour, but the average Leonid meteor shower has a peak every 33 to 34 years, and the number of meteors can exceed thousands per hour. The most recent peak was in 2001, with as many as 3300 meteors per hour wandering around.

According to astronomers, "Leonid" meteor shower is not a meteor in "Leonid". In order to distinguish meteors from different directions, it is usually named after the constellation in the sky where the meteor shower radiates. And the Leonid meteor shower is the radiant point of the meteor shower in Leo.

In 1998 and 2001, the Leonid meteor shower left a very good memory for countless astronomical enthusiasts. But in recent years,Its maximum hourly zenith flow (zHR) rarely reaches more than 20。 It is predicted that by the end of this century, a large-scale Leonid meteor shower will occur.

In addition, the Geminid meteor shower in December is also worth looking forward to.Geminid meteor shower is one of the major annual meteor swarms, active from December 4 to 17。 Experts said that the maximum forecast period of this year's Geminid meteor shower occurs on December 14, and the maximum hourly zenith flow rate of meteors is predicted to reach 140.
