It's not possible to fit anything "inside" Uranus, because it's a gas giant! It doesn't have a solid surface like Earth.

Here's why:

* Gas giants are mostly made of gas and ice: Uranus is primarily composed of hydrogen, helium, methane, and other trace elements. It has a small, rocky core, but the vast majority of its volume is made up of gas and ice.

* No solid surface: Because of its gaseous composition, Uranus doesn't have a defined surface like Earth or Mars. You would sink deeper and deeper into its atmosphere if you tried to land on it.

So, while it's fun to imagine, fitting things inside Uranus is impossible because of its nature as a gas giant.
