Comets are like ice balls that shine when they get close to the Sun. Imagine you have a big snowball made of ice and dirt, and it’s traveling through space. When it gets near the Sun, the heat makes the ice melt and create a glowing tail, that's what we see in the sky! Asteroids are more like rocks that don’t have ice, so they don't shine as much when they come close to us.
What Comets Are Made Of
Comets are mostly made of ice and dirt. When the Sun heats them up, the ice turns into gas and forms a tail behind them. This makes comets look like glowing streaks in the sky.
What Asteroids Are Made Of
Asteroids are usually just big rocks that float around space. They don't have ice, so they don’t glow or form tails when they come near us.
Examples
- A comet is like a snowball that glows when it gets close to the Sun, imagine a big ice ball making a bright streak in the sky.
- An asteroid is more like a rock floating through space, it doesn’t glow or make a tail, just looks like a small dot.
- If you’ve ever seen a comet in the night sky, it was probably a giant icy rock melting and glowing as it came close to Earth.
