Neptune's orbit takes 125 years to get around the sun.
Planet Xena, also known as Eris, takes about 557 Earth years to complete one orbit around the sun.
A "year" is the time it takes for the earth to orbit the sun. Each planet has it's own year. A "day" is how long it takes for the planet to spin all the way around.
The length of a planet's orbit around the Sun varies depending on the distance from the Sun. For example, Mercury has an orbit of about 88 Earth days, while Neptune's orbit is around 165 Earth years.
It takes 687 days for the planet mars to orbit the sun.
365.25 days
It takes Jupiter approximately 12 years to orbit the sun.
Mars completes one orbital revolution around the sun in 687 earth days, or 1.88 earth years.
A year on Mercury, in terms of the time it takes for the planet to complete one orbit around the Sun, is approximately 88 Earth days. This is due to Mercury's closer proximity to the Sun and its faster elliptical orbit.
