All the planets orbit the sun in the same direction that they were spinning when they formed. Which of these laws describes why this is the case?
For every action there is an equal and opposite reaction.
An object at rest stays at rest unless acted upon by an outside force. An object in motion remains in motion unless acted upon by an outside force.
Each planet in the solar system is a different distance from the sun. The distance is proportional to the length of time it takes a planet to orbit the sun.
Planets moves fastest when they are closest to the sun and slowest when they are farthest from it.
