Most meteors are small, ranging in size from a grain of sand to a pebble, and they typically burn up completely before reaching the ground. However, larger meteors can produce spectacular fireballs and may even survive the journey to become meteorites if they land on Earth's surface.
Meteor showers occur when Earth passes through debris trails left behind by comets, resulting in an increased number of meteors visible in the night sky. Studying meteors provides valuable insights into the composition of our solar system and its history.
