Orbit Lengths. In the time it takes the Earth to complete one orbit, the planets closer to the Sun (Mercury and Venus) orbit at least once. The more distant planets (Mars, Jupiter, Saturn, Uranus and Neptune) which move slower and have a greater distance to travel, complete just a fraction of their orbits in this time.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
