Question

medal and faned Yuri built a model of the solar system on his desk. But, it is not exactly the same as the real solar system.

What limits his model from being exactly the same?
Yuri is not able to use a model to show all eight of the planets.

The Sun is a big star and he cannot make a model of a star.

It would be hard to make a model that shows the real sizes and distances between planets.

He would not be able to make a model that shows the colors of the planets.
