Comet nucleus

A comet nucleus is like the head of a comet, just like our heads are at the top of our bodies. It's made up of ice, dust, and rock, which is like the ingredients we use to make our favorite treats.

When a comet gets close to the sun, it heats up, and the ice starts to turn into gas. This gas and the dust and rock around it form a big ball-like shape that we can see from Earth. This ball is the comet's coma.

But inside the coma, there is a small solid center called the comet nucleus. It's like the cherry or candy center of a treat. Scientists study these nuclei to learn about how comets form and what they're made of.

It's really important to study comets because they've been around for billions of years and can help us understand how the solar system was formed. Plus, comets are really cool to look at!
