Yes. Everything in the Universe is related to motion and physics.
Uranus is related to the solar system because it is a planet.
Please be more specific about which solar system.
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
The sun has no motion because it is at the center of our solar system
The Sun.
The laws of physics and the evidence of the extant solar system as observed today.
Rotation and revolution.
Retrograde Motion
Well, seeing as he was a Mathematician and Astronomer, he is closely related to the Solar System. During the Scientific Revolution of the 17th century Johannes Kepler discovered and documented the laws of planetary motion. His studies also laid the groundwork for Isaac Newton's theory of universal gravitation.
The same as they are in yours. :D
retrograde motion
Gravitational forces combined with the motion of the planet or moon originating from the formation of the solar system.
