Comets are like ice balls made of frozen dirt and gas, and they travel through space for a really long time. When they get close to the Sun, it starts melting them, but comets don’t just melt away because they have something special inside them that helps them survive.
Why They Don’t Melt Away
Comets are not just ice balls; they also have dust and gas mixed in. This mix gives them a kind of protection, like wearing a coat on a cold day, even if the outside starts to melt, the inside stays cool enough for the comet to keep moving through space.
Also, comets are not always near the Sun, they come close only once every few years or even centuries. So even though it feels like they're getting super hot, they have time to rest and recover before their next visit.
Examples
- A comet is like an ice cream cone that melts in the sun, only part of it melts away, and the rest stays frozen for a while.
- Imagine wearing a coat on a warm day, even if you start to sweat, your body doesn’t melt completely.
- If you left an ice cube near a lamp, it would start melting, but not all the way through.
