The study of meteoroids provides valuable insights into the composition and dynamics of our solar system, as well as the potential hazards they pose to spacecraft and Earth.
Meteoroids often originate from comets or asteroids and can range in size from tiny particles to objects several meters in diameter.
Most meteoroids burn up completely in the atmosphere, but larger ones may survive and reach the Earth's surface as meteorites.
When a meteoroid enters Earth's atmosphere and vaporizes due to friction with the air, it creates a streak of light known as a meteor or shooting star.
A meteoroid is a small rocky or metallic object in outer space that is significantly smaller than an asteroid and larger than a micrometeoroid.
