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

|| ✪ 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,

[tex]T^{2}[/tex] ∞ [tex]r^{3}[/tex]

[tex]T^{2} =kr^{3}[/tex]

[tex]T=\frac{3}{2}[/tex]

Here, the constant k is taken to be 1.

Substituting the values, the orbital speed will be

[tex]T=(10)\frac{3}{2}[/tex]

[tex]=31.62~years[/tex]

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