A meteorite is a solid fragment of a meteoroid that survives its passage through Earth's atmosphere and lands on the surface. Meteoroids are smaller celestial objects, typically ranging from the size of a grain of sand to a few meters in diameter, and when they enter the atmosphere, they produce a bright streak of light known as a meteor or "shooting star." If the meteoroid survives the intense heat and pressure during its descent and reaches the ground, it is classified as a meteorite. Meteorites can provide valuable insights into the composition of celestial bodies and the early solar system.
