Frequently Asked Questions
The Leonid meteor shower is active annually from approximately November 6th to 30th, with peak activity typically around November 17th or 18th.
They are named because their radiant—the point in the sky from which they appear to originate—lies within the constellation Leo.
No. Leonids are typically small particles of dust and ice that burn up completely in the Earth's atmosphere, posing no threat.
Major Leonid meteor storms, with thousands of meteors per hour, occur in cycles of approximately 33 years, coinciding with the perihelion passage of the parent comet, Tempel-Tuttle.
