Meteor
In space and astronautical engineering, a meteor is a small rocky or metallic object that enters the Earth's atmosphere and burns up, producing a streak of light in the sky. Meteors are also known as shooting stars or falling stars. They are typically the size of a grain of sand or a pebble, but can be as large as a boulder. Meteors are formed from debris left behind by comets or asteroids. When the Earth passes through a trail of this debris, the particles collide with the Earth's atmosphere, causing them to heat up and glow. Meteors can be observed from the ground with the naked eye, and are often seen during meteor showers, which occur when the Earth passes through a particularly dense trail of debris.
