1. Regular Features of the Solar System
All of the planets orbit the Sun in the same plane
All planetary orbits are nearly circular
All planets orbit the Sun in the same “direction”
Most planets rotate in the same sense as the orbit.

3. Regular Features of the Solar System
The Jovian and Terrestrial planets are well sorted in terms of distance from the Sun.

4. Regular Features of the Solar System
The Giant Planet satellite systems resemble the Solar System

5. Regular Features of the Solar System
Exposed solid surfaces are heavily cratered throughout the Solar System.
The process was messy and produced lots of leftovers.

7. Building a Solar System through “Accretion”
These regular features are “fossilized” memory of the conditions that gave rise to the Solar System.
In sum, they suggest the planets grew within a rotating flattened disk and, today, their orbits reflect the structure of that disk.
