Meteorites are rocks that originate in outer space and land on Earth. They are formed when asteroids and comets break apart and their fragments enter Earth's atmosphere.

As the fragments hurtle through the atmosphere, they heat up and glow, creating a streak of light in the sky known as a meteor. If the fragment survives the journey through the atmosphere and lands on Earth, it becomes a meteorite.

Meteorites can range in size from tiny particles to large boulders, and they can be composed of various materials, including rock, metal, or a mixture of both. Some meteorites contain valuable information about the history and evolution of our solar system, and scientists study them to gain insights into the composition and origins of celestial bodies.
