Comets are like dirty snowballs that zoom through space. When they get close to the Sun, the heat makes their ice melt and release gas and dust. This creates a glowing tail that we can see from Earth.
Why It Happens A comet's tail is made of [two parts](/search?q=two%20parts): one made of dust and another made of gas. The [sunlight](/search?q=sunlight) pushes these materials away, making them look like long, bright tails.
Examples
- A comet is like a dirty snowball that gets warm near the Sun, melting its ice and creating a glowing tail.
- When you walk in front of a light, your shadow stretches out, comets are kind of like that, but with gas and dust instead of shadows.
- Imagine blowing on a candle flame from across the room, that's how sunlight pushes away the gases and dust to make tails.
