What Causes a Comet to Have a Tail?

Comets have tails because they are like dirty snowballs in space. When a comet gets close to the Sun, it starts to melt and release dust and gas. These materials are pushed by sunlight and wind from the Sun, making them trail behind the comet, just like when you walk through a sprinkler and water follows you.

Examples

A comet is like a snowball that melts in the Sun, and when it does, its melted parts float away behind it like confetti.
Imagine walking through a sprinkler on a sunny day. The water follows you like a tail, just like how comets leave tails behind them.
If you put an ice cube in a microwave, it might start to steam, that’s the comet melting and releasing its dust.
