Tiny Models Loli What Is The Proper Name For Models Of The Solar System And Gyroscope Objects?

What is the proper name for models of the solar system and gyroscope objects? - tiny models loli

I mean the kind of model of solar systems with the sun in the center and the planets in the arms of little metal in orbit, and the end of the movie Tomb Raider, or the smallest model in black.
The gyroscope, what I mean, like giant machinery inside in the movie "Contact", where the rings are rotated.
Thanks for any help.
