Do gas giants actually have a solid core? If so, how big are they usually?
In: 343
Gas giants, like Jupiter and Saturn, are pretty cool and mysterious planets. Imagine a big balloon filled with air, but instead of air, it’s filled with lots of gases like hydrogen and helium. These gases keep swirling around and make the planet look like a colorful marble from far away.
Now, let’s talk about the core. Yes, gas giants do have cores, but they’re not solid like a rock. Instead, the core is more like a super squished and compressed ball of stuff. It’s like if you could squeeze a soft sponge really, really hard until it becomes very dense.
The cores of gas giants are made up of heavier stuff, like rock and metal, which is hidden beneath all the layers of gases. But because these planets have such strong gravity, the gases on the outside are really heavy, and they press down on the core, making it squished and dense.
As for how big the cores are, they can vary. Scientists think that the cores of gas giants are quite a bit smaller than the whole planet. For example, Jupiter’s core might be around 20 times the mass of Earth. That might sound big, but remember, the whole planet is super huge compared to Earth.
So, even though gas giants don’t have solid cores like a rocky planet, they definitely have something dense and heavy at their center that helps make them the fascinating planets they are!
