hankey-meteorSky-watchers, take note: the Leonids meteor shower, which occurs once a year in November, will illuminate the heavens late Sunday night through early Monday morning. Bill Cook, head of the Meteoroid Environment Office at the Marshall Space Flight Center in Huntsville, Alabama, said in an interview with Space.com that roughly 10 to 15 meteors will flit across the sky per hour during this year’s shower. The Leonids are one of about 12 major meteor showers that happen every year. The difference between major and minor showers has to do with how many meteors shoot across the sky per hour; two other major meteor showers, the Perseids and the Geminids, boast 100 and 120 meteors per hour, respectively. Any meteor shower, this one included, has the potential to evolve into a full-on meteor storm. The last massive Leonids meteor storm happened in 2002, where roughly 3,000 meteors per hour shot into the sky, reports National Geographic. More
