History

Historical Context

In 1994, the International Astronomical Union established a meteor shower classification system, categorizing showers based on Zenith Hourly Rates (ZHR). This system aids novice astronomers in identifying optimal viewing opportunities, enhancing public interest in astronomy. Historically, significant meteor events, like the Great Meteor Storm of 1833, have shaped our understanding of meteors as cosmic debris, fostering educational initiatives around celestial phenomena.
