they all follow the laws of physics (conservation of energy, of mass, etc)
biggest to smallest : universe, galaxy, star/solar system, planet, moon. The Universe is everything that exists and a galaxy is a cluster of billions of stars and then planets rotate around stars and moons rotate around planets.

Our solar system is about 2/3 of the way out one of the spiral arms of the Milky Way galaxy, well out from the center. Because of the apparent expansion of the universe, we are unable to determine where the Milky Way galaxy is with reference to any 'fixed" reference; there appear to be no fixed references in the universe.
Universe >> Milky Way galaxy >> Solar System > Sun >> Earth
There are eight planets, including Earth, in our solar system, there are many solar systems in our galaxy, and there are countless galaxies in the universe.
The Solar System contains the Earth-Moon system. The Milky Way galaxy contains the Solar System. The Virgo supercluster contains the Milky Way galaxy. The Universe contains the Virgo supercluster.

Generally speaking people thought the earth was central in the entire universe. This was proven wrong many times, most important proofs were: - Proof that the earth is not central in the solar system - Proof that the earth is not central in the galaxy - proof that the galaxy is not central in the universe
