Meteoro

The video tutorial explains the differences between meteoroids, meteors, and meteorites. Meteoroids are small particles from comets or asteroids that orbit the sun. When they enter Earth's atmosphere, they become meteors, creating a streak of light in the sky. If a meteor survives its journey through the atmosphere and lands on Earth, it is called a meteorite. The video also discusses meteor showers, which occur when Earth passes through a comet's tail, causing numerous meteors to appear. The tutorial highlights the composition and size of meteoroids and the rarity of meteorites reaching scientists.
