Comets and meteors both have the word 'star' in their Chinese names, but they are completely different things! A comet is a huge 'space ice block' in the solar system that orbits the Sun, trailing a beautiful long tail when it gets close. A meteor, however, is a playful little space rock or piece of dust. When it streaks into Earth's atmosphere, friction makes it glow brightly for just a split second before it disappears—that's when we often close our eyes and make a wish. Little Panda tells you: Beautiful meteor showers happen when Earth passes through the trail of debris left behind by a mother comet. So, a comet is like a mother, and the meteor shower is the 'shiny shower of her children'!
