What is the significance of the Leonids meteor shower?

The Leonids meteor shower has its radiant, or point of apparent origin, in the constellation of Leo. Roughly every 33 years, the Leonids display impressive storms of thousands of meteors per hour. The 1833 storm was so spectacular that some described the meteors as like “snowflakes.” The Leonid meteor stream is associated with Comet Tempel-Tuttle.
