The orbital period is 31.62 years when the average distance from the sun is 10AU

|| ✪ Step-by-step explanation✪ ||

Given:

The average distance of the planet from the sun is r = 10 AU

To find the orbital period.

According to Kepler's third law,


T^(2)
r^(3)


T^(2) =kr^(3)


T=(3)/(2)

Here, the constant k is taken to be 1.

Substituting the values, the orbital speed will be


T=(10)(3)/(2)


=31.62~years

Final Answer: The orbital period is 31.62 years when the average distance from the sun is 10AU

Hope this helps!
