This chart illustrates the vast differences in orbital periods, showing how a "year" ranges from just 88 days on Mercury to 165 years on Neptune.

- The Sun is a star that provides light and heat to the planets in our solar system.
- Mercury is the closest planet to the Sun and takes 88 days to orbit it.
- Venus is the second planet from the Sun and takes 224 days to complete one orbit.
- Earth is the third planet from the Sun and takes 365 days to orbit, which defines one year on Earth.
- Mars is the fourth planet from the Sun and takes 687 days to orbit.
- Jupiter is the fifth planet from the Sun and takes 11.8 years to complete one orbit.
- Saturn is the sixth planet from the Sun and takes 29.6 years to orbit.
- Uranus is the seventh planet from the Sun and takes 84.3 years to complete one orbit.
- Neptune is the eighth planet from the Sun and takes 165 years to orbit.
- The farther a planet is from the Sun, the longer its orbital period (year) due to the greater distance it must travel and the weaker gravitational pull from the Sun.
