As Pluto is so far out in comparison to a Earth to the Sun. It takes a much longer time to get around the sun so its year are much longer. You can work out the length of a Plutonium year by using (G*mass of the sun)/radius form the sun to Pluto= the speed of Pluto squared. Which is 6.67x10^-11*2.00x10^30/5.9x10^12= 5165.27 ms-1 so then we can work out the circumference of the orbit find out how long it takes. the circumference is 3.

7x10^13 so t=3.7x10^13/5165.27=7163226705 seconds or 82907.7 days which is equivalent to 227 Earth years. I hope this helps
