When's the next meteor shower(流星雨）？The time of meteor showers does not change much from year to year,though the peak(高峰) of a shower may differ within a day or two. We've listed the best watching time for each shower in 2022,along with the number of meteors per hour.

　　Quadrantids(January 3-4)

　　The Quadrantids are one of the best meteor showers,as there are about25 meteors per hour at their peak. The Quadrantids' peak is quite short, lasting from about midnight to dawn,but the number of meteors makes the experience worthwhile.

　　Lyrids( April 21 -22 )

　　You can expect to see about 10 -20 meteors per hour in dark, clear skies between midnight and dawn. This meteor shower can be watched from both the Northern and Southern Hemisphere（半球），but is much more active in the Northern Hemisphere.

　　Delta Aquarids( July 28 -29)

　　As a weaker shower,the Delta Aquarids produce between 10 and 20 meteors per hour around late July. A truly dark sky offers the best chance of seeing the Delta Aquarids,as they are not as bright as the other meteor showers.

　　Perseids( August 11 - 13)

　　Thanks to a high MPH(meteors per hour) and the August weather,watching the Perseids is one of the best meteor-viewing experiences. There are about 50-100 meteors an hour. Unluckily,this year,they will meet with the full moon, which rises on the night of August 11. Its brightness will wash out the Perseids, so you have to catch the chance before dawn.when the moon is closer to setting.
