1. Physical properties of the planets vary in a systematic fashion as a function of distance from the Sun.
Planets and Sun revolve and orbit in a west-to-east direction. The planets obliquity (tilt of rotation axes to their orbits) are small. Uranus and Venus are exceptions.
The planets differ in composition. Their composition varies roughly with distance from the Sun: dense, metal-rich planets are in the inner part and giant, hydrogen-rich planets are in the outer part.
The Moon include its distance from the Earth, size, mass, density, and temperature
2. Asteroids - large, rocky bodies
Comets - smaller, made of ice, rock, dust
I don't know if this is what you want, but please please correct me if I'm wrong!! :)
