Meteor showers
A meteor shower is a celestial event where numerous meteors appear to streak across the night sky from a single point. These meteors are created when streams of cosmic debris called meteoroids enter Earth's atmosphere at extremely high speeds. Most meteors are smaller than a grain of sand and burn up completely before reaching the ground. Meteor showers matter because they represent a direct connection between Earth and comets, helping astronomers understand our solar system. They also provide spectacular viewing opportunities that have captivated human observers for thousands of years, dating back to ancient China, Korea, and even Sparta. Named meteor showers return predictably each year at approximately the same dates, making them accessible targets for both casual stargazers and scientific study.

- en.wikipedia.org: “A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth's surface.”
