Leonids radiant

The Leonids is an annual meteor shower that reaches its maximum on November 17–18 and has its radiant point in the constellation Leo, near the center of the Sickle asterism. The shower provides modest displays in most years but spectacular meteor storms every 33 years; rates of 60,000 meteors per hour were recorded in 1966.


The Leonids are fast-moving meteors, entering Earth's atmosphere at about 250,000 kilometers per hour, and leave many trains. Their parent body is the comet Tempel-Tuttle.
