It takes Mars 1.9 Earth years to orbit around the Sun.
Saturn takes around 29 3/4 earth years to orbit fully around the sun
Neptune's orbit takes 125 years to get around the sun.
164 earth years
Pluto takes about 248 Earth years to complete one orbit around the Sun. Its long orbit is due to its distance from the Sun and its slow speed of movement.
164.8 Earth years
It takes 84 years for Uranus to go around the sun.
2 years
Possibly hundreds of thousands of years.
If you mean Pluto, that's about 248 years.
actually to brake it to you scientist haven't discovered that out yet but scientist are pretty sure it has a long orbit :)
Jupiter has an orbital period of 4,331.5 Earth days or about 11.86 years. Its orbit is much longer than Earth's, and it also moves more slowly in its orbit. Jupiter's orbit is roughly 11.86 Earth years long.
Nobody actually knows how long it took for Neptune to form because it is so far away. We can not take samples to test how old the rocks are either because our equipmen can't make it through the methane atmosphere.
