Inertia is an object's resistance to change in motion. In other words the difficulty in moving an object or stopping it from moving. A heavier car has more inertia than a lighter car because it's harder to move. A faster car has more inertia than a slower one with equal mass because it's harder to get it to stop.
So the more inertia a car has, the more dangerous it is in a collision.
The inner planets are usually rocky because the gravitational pull is stronger closer to the star or in this case the sun. The dust and rocky particles that are left over after a super nova or in a nebula will tend to orbit closer to a proto-star when a solar system is in its early days. In our solar system these planets are Mercury, Venus, Earth and Mars. Gases are less dense and will be less affected by the pull of gravity because rocky particles have more mass. The outer planets are gas giants formed from clouds of gas that would be further out in the spinning disk around a proto-star.
The seasons basically wouldn't change, because basically only one spot would be facing directly at the sun the whole time, so it would be summer there forever, and the edges that barely get any sun would be in eternal winter.
