The Leonid Meteor Shower is an annual celestial event that occurs every November. It is caused by the Earth passing through the debris left by the comet Tempel-Tuttle. As these tiny particles enter the Earth's atmosphere, they burn up and create bright streaks of light in the sky, known as meteors. The Leonid Meteor Shower is famous for its impressive displays, particularly during years of high activity, when viewers can see dozens or even hundreds of meteors per hour. The best time to observe the shower is usually in the pre-dawn hours, when the sky is darkest and the meteors are most visible.
